## Questions & Answers

**Q: Says "requires paid tv guide for dvr record", so all recording is totally disabled unless you pay?**
A: Just received my order.  Attached and it formatted USB drive.  Even though the app allows me to setup to record shows, no recording was performed.  Under Account Info, showed DVR is not active.  After googling, HDHomeRun's web page said subscription ($35/yr) is required if want to use DVR on HDHomeRun ("not required if you are using third party DVR software/service" like Plex).

**Q: Router in garage, indoor antenna best by far away window, no ethernet ports in house, coax outlet only. Can I make this unit work?**
A: I don't know how you'd do that without an Ethernet connection.  This is designed to take "off air" programs by way of an antenna and provide them on an Ethernet connection so that you can either control them with a server (which is often acting as a DVR), or with a network direct connect to your streaming box or Smart TV.   If you're running your network using Wi-Fi for streaming, and you have an Ethernet connection in your garage on your router, you could plug it in there.  Long coax runs from an antenna can exhibit loss, so it's difficult to assess how well that would work since I'm not actually there, I can't comment.  If you can get good TV signals off coax in the garage, then it should be able to work through your router.

**Q: Can you record two channels while watching a recorded show?**
A: Yes, you can record two channels while watching a recorded show. Recording requires a USB hard drive and TV guide ($35/year).

**Q: I have an 8k av receiver w hdmi 2.1. i want uncompressed ota tv with a guide. no need to record/stream. prefer no atsc 3. what are options?**
A: Any SiliconDust tuner.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well as a tuner for a Plex Server TV/DVR source
*by T***M on August 29, 2025*

Setup was reasonably straightforward despite the fact that their web interface is pretty clunky. The Android app seems to work well but I purchased this to feed my Plex server running on an Asustor NAS AS540Z1 and, as such, have not connected external storage. Plex recognized the tuner immediately and, as long as you remember to identify a directory to store DVR data in setup, works well without a lot of headache.The tuner seems to be a bit more sensitive than a Tablo that I also have, time will tell if it's more stable. (Tablo is still a good product but is famous for instability in HW and apps. I have a remote power switch to reset the thing to make life easier when it locks up)It was much easier than the Tablo to set up. and, unlike Tablo, has a web interface to watch on the PC although it appears to have been written by engineers that were rushed to get something out the door.I have not tested HDHomeRun through it's dedicated Roku app but the HDHomeRun shows through the Plex app running on Roku works well.The 2-tuner version was purchased as an experiment but if ATSC3.0 ever rears it's ugly head, I'll likely spring for the flex 4K version.

### ⭐⭐⭐⭐⭐ Amazing little piece of equipment (Detaild review with some instructions)
*by S***8 on September 13, 2023*

I only give five stars and take my time to write detailed reviews when something is deserving. And you should buy it. In this case, this little piece of tech has far exceeded my expectations. The reason for that is I have a first generation Haupage, and I have never been able to get more than a couple of channels.I've been in the tech world over 40 years, am a Broadband and Network Engineer going back to 2001, and cut the cable about ten years ago. Biggest problem, without paying fees, is real time news on TV. Yea, you can get real time local news streaming (For a fee in our case) or watch it on a computer, but we do prefer having it on TV. There are also some network TV shows my wife likes, streaming they are always a day late. She would like to watch them when they are on. And this device was the ticket.I watched quite a few videos on how to get the best reception with this device. In short, 45 miles away on a single hill with multiple towers, they broadcast 40 channels. As noted I was never able to get more than 2 or 3 even with the most expensive powered antenna. My RV has an integrated raise. Lower antennae and can get 8 from my backyard. After connecting this device, properly, I get all 40 channels crystal clear. I bought this device fully expecting to see it not work and send it back. Nope, definitely keeping it.Here are step by step instructions, I took from multiple videos, on how to get the most channels and best reception. But first a couple of notes. After setup, I will go over some of the features of this little box and the app. You can ignore some of the older review complaints, because as I learned (Again watching videos) there have been more than a few updates and I can verify you do not need a Plex server or anything else. More on that after installation.I have a hardwired house with a network room, server, couple of cabinets etc, so for me I can make it work anywhere in my house. I am not restricted by a modem/router. I will make some notes on that as I go along.1. Find your broadcast towers. There are multiple websites you can use, I used Channel Masters and two others to get exact location. I found that 40 channels were broadcast from a hill in one city and 3 more were broadcast within range from a different direction. I cannot get those three channels. It doesn't matter because I get all the local and networks on the 40.2. Download a map compass on a cell phone. I used an app called Compass Maps for Android. You may or may not have to download the map in addition to the compass. I did, works great, going to keep it. That is unless you already know the exact location of your broadcast towers.3. Locate the window in your house closest to pointing directly at those towers. A couple of notes.* Walls will severely restric reception.* Clear glass is good, this will still work if you have screens, but screens will restrict reception. In a storm window with a screen, I recieve about 15 of the 40 channels available, moved over one window, center, no screen, 40 channels.4. If you have an amplified antenna, do not use the amplifier. Thread the antennae directly onto the HDHomerun. Amplifiers severely interfere and restrict reception through the tuners and are not needed. And of course if you do not have an amplified antenna, don't buy one for this, not needed.5. Thats it, for best reception put your antenna in a window facing as close as possible in the direction of your broadcast towers, plug it in to your network or router. Then download the HDHomeRun App on any or all devices.Note that this should be obvious but two tuners means you can only watch on two devices at once. But you can set it up on as many devices as you want, in my case it is set up on nine devices, including multiple big screen TV's, several computers and a couple of cell phones. It works perfectly through all of them.This works through any type of network configuration, wireless router (with jacks), hardwired home network or Powerline Adapters, I have netgear powerline adapters running in a couple of rooms off of my network and tested, works fine, no problem.The AppI nearly ignored the app based on old complaints until watching a video that showed the complaints had been addressed. It is not hard to use and has a lot of new functions. (I do not know how the old App was since I have not used it, so I have to take other people's word for it).Once you download and install the app on your Smart TV or streaming device you use your normal remotes as usual. There is no separate remote for this device.You do not have to create an account to use the app, and there are no fees for anything.Once you click on the app you will see:Version (You do have the option to upgrade firmware through your account. I did that)Using ASymch Platform APIIt searches and then "Found 1 Device"Then device number and HD Homerun" followed by booting to the main screens.Total boot time for my devices is no more than about ten seconds.It will boot to the last screen you were watching, including if you logged out while watching a channel/TV program.Your first screen is your "Live Screen". Pressing theup or down arrows on your remote displays all of your channels and moves up and down through the channels. It may take a couple of seconds to populate all the channels.On the right side, all of your channels, each channel shows what is currently playing on that channel with a screenshot along with channel, 3.4, 3.3 and so forth.On the upper left side of the screen it will show time, Channel and current TV show playgoing.on the very top right of the screen are five icons. Search, favorites (Star you can click to lock that channel/show as a favorite, return to last icon, a newspaper icon that bring up only the news channels, a football icon that brings up only the sports channels, and a movie (film) icon that brings up only movies.Bottom is your fast forward, reqind, pause (You can fast forward, pause and rewind live TV with this app), your SAP, CC, Zoom, full screen and "Discover" Icons.Hitting the Discover Icon takes you to the Discover Page which is a full screen guide of TV shows, movies, sports, news, documentaries etc., you can select any of them, select a time when they will be on and set to record.Note you do not need an account to record, you can attach up to a 2TB drive to this device for recording.Above the full screen guide are four options. Now (Which it will be on automatically), Shows, Movies and Sports and clicking any of them will show only those categories in the guide.Above that are four options. Live, Recorded, Discover and Tasks.Live takes you back to the main page where you can watch whatever is on live TV.Recorded is self explanatoryDiscover shows you the guide with everything that plays on every channel. Clicking on any show, sports event, or whatever gives you the option to record an entire series or multiple events.Tasks shows whichever tasks you have selected, Record, playback and others while an "Upcoming" shows just that, upcoming tasks.Clicking "Live" at the top of any screen other than the main "Live" screen takes you back to the live TV screen.Note on the top right corner of any screen other than the Live screen is a settings icon. In the settings you can do the following.See account informationSee devices and device serial numberSee a list of all available channels and select any number of them to add to favorite channelsSet parental controls including adding a PinSet your Start Page to any channel you want on bootupThe guide on the Live page is called the Live TV slice guide (Ill explain further down), you can turn it on or off.Set your speaker configuration. There are multiple surround sound options, Digital Passthrough and othersSend Diagnostic Information (On/Off)The very bottom is early access to new features. For me, I am keeping it off because have seen more than one person get a firmware update and brick their device.The Live Slice TV Guide on the "Live Screen". On your remote, you use the up and down arrow buttons to open the guide and right and left arrow buttons to see more information for whichever channel you are watching. Clicking right on your remote arrow key will show you the next 1,2,3,4 and 5 shows coming on, on that particular channel, with a synopsis of the current show and a synopsis of the next five. You can click to see 1 through 5, whatever you want. If you click on any future show, it will give you the option to record that show. Clicking the left arrow button closes the guide to the show you are watching.To clear the screen of the Live Slice Guide, simply click your back button.How satisfied am I with this device. Solid Five Star satisfied.Easy to set upWorks great with any type of networkUses basic antenna's, no amplified antenna neededCrystal clear pictureGreat app with a lot of optionsCan connect up to a 2TB hard drive.Quick Edit: When I first purchased it recorded without an account. Then it stopped and I had to add an account and purchase the annual subscription. The subscription IIRC is $27 (give or take a few dollars) annually and worth every penny. On the original recordings I really had no control over it and could only delete directly from the drive. Having the account with the DVR service gives me full control and makes the low cost annual fee worth every dime.

### ⭐⭐⭐⭐ Essentially works fine but with caveats
*by S***A on March 24, 2024*

I purchased this to reposition the digital on air antenna for our TV without having to run wires/cables. It's been quite good at achieving that goal. I positioned our old antenna by a less obstructed window and wired to the HD tuner and then to the router. From this position, the antenna picks up all the local channels great (including a few I could not see before). In fact, I was thinking of getting a new powered antenna eventually, but I think the receiver in the device is better than what my TV had. The quality of the video play-back is generally great. Being able to watch on multiple devices is a nice bonus. It is not perfect though because of a few issues:1) The TV apps (Roku, windows, Apple, Android, etc.) have some glitches. The display settings on the apps are not the same across devices. Some features are not possible in one environment or another, and the user interface is a bit clunky at times. On the mac, sometimes if I minimize the app window when it is set to "be on top", it flips to an earlier channel. There are times the audio seems a little off (lags), you cannot rewind live TV on Roku, etc.2) The Roku app was a challenge to set-up. I could not get audio for quite a while. After a lot of trouble shooting, it was a matter of changing some settings on TV and Roku (basically disable the auto-volume adjust for the app, Roku, and TV) and it finally worked. But, boy, that was a huge hassle to set-up. Searching for solutions online was not as straight forward.3) My biggest worry is the device security. Until now, I had put most internet enabled devices (TV, security cameras, dryer, etc.) on my guest network and not on my main home network. Unfortunately, this device has to be hardwired to your router, which mostly means on your main network on the router. This also means, I have to have my Roku device on the main network (rather than a guest network that prevented devices from seeing each other and the router). I am pretty sure 95% of users don't care about this, but I am personally not happy with this set-up. I think it creates a security hole to my network from both the Roku device and the Silicon Dust tuner. Roku is a big enough company I hope I can trust, but I have no idea whether SiliconDust will keep their device secure. If you care about such things, be forewarned that you are opening your home network to the outside. I just hope their platform is not very hackable and their device OS does not have a generic admin password...
