  • Great product, outstanding tech support
My experience with this product began with a phone call to Silicondust tech support, pre-purchase. The call was returned quickly and all questions answered thoroughly and politely. Talk about not feeling rushed off the phone, I felt a little guilty for taking up so much time. But, I'm not the most tech-savvy and was looking to "cut the cord". The item was ordered within minutes of concluding the tech call. Setup was easy and intuitive. The unit works very well with the current gen Firestick, as well as a Vizio remote. Oddly enough, the LG app is nearly worthless, DVR menu and functions don't show up and the seasons change quicker than TV channels. The Firestick fixed those issues. A second call to tech support was needed to get the DVR capabilities working. Again, setup was quick and easy. I added a $50 Toshiba 1Tb HDD. This thing has a very good tuner. In direct A/B comparisons to the Vizio tuner, freception of marginal stations is far better and it pulls MORE channels, including the low-power channels 40-50 miles away. Oddly enough, when atmospheric conditions are favorable, I can get stations in excess of 80 miles away, some over 100(!). Where the television can pull 54 stations, the Silicondust tuner pulls 82, 74 of which are usable. I'm using a Televes 148383 Datboss antenna, in an attic location, approximately 22 feet elevation. Quite a few comments are at least somewhat critical of the user interface, especially the program guide. In my opinion, it's roughly equivalent to using a cable provider's DVR. There are tradeoffs but they are just different, not really better or worse than any other DVR. There's always a learning curve, no biggie. The lone criticism I have is the lack of ability to set recordings by channel/date/time; that would be a really nice addition. As it is, scrolling is reasonably quick, so no harm/no foul. The weakest aspect is the website and lack of instruction manual. It'd be good to have the option of a downnloadable .pdf. Coming up on two weeks in-service, I am still discovering capabilities that are undocumented and they're all good. Via computer and smart phone, the Homerun app is nice to work with, especially in terms of recording and FF/REW functions when playing recorded content. Overall, a satisfying purchase. Would recommend to anyone looking for a good OTA DVR. ... show more

  • Beautiful Picture; Poor Interface
My wife bought me this tuner for Christmas, and I added a 2 TB USB external drive for recording. The picture quality on live viewing and recordings is excellent on both the ATSC 1.0 and NextGen TV ATSC 3.0 channels. The user interface is not intuitive, not quite "user hostile" but also not fully user-friendly. Some comments on the tuner: - I had been using an Amazon Recast previously. The Recast connected to wi-fi wirelessly, and the HomeRun connects via ethernet cable. The hardwired connection is 100% reliable (no dropouts or disconnects), is faster, and the picture is significantly better. - Recordings in ATSC 3.0 have skips and dropouts in both video and audio that do not seem to be present in the ATSC 1.0 recordings. - The external drive is not formatted in NTSC, so it cannot be read directly if plugged into a Windows computer. It can be read from a Linux computer, or a dual-boot Linux/Windows device. Recorded programs also can be copied on the network from the external drive treating the tuner as a network device. - Audio in the ATSC 3.0 recordings, if copied from the external drive, does not play on VLC or Media Player. NextGen TV uses a codec called AC-4, which is not widely available. Playing back through the SiliconDust interface plays the audio properly. - I paid for the 14 day electronic program guide, but only a day or so was displayed at a time. I found out from SiliconDust Tech Support that it is necessary to go to the maximum extent of the guide, exit the app, and restart it to get more future listings. They admitted this needs more work. - Overall navigation in the SiliconDust app is awkward when moving between Live TV, the guide, and recordings. As a result of my dissatisfaction with the SiliconDust interface software, and to provide a more intuitive interface, I investigated Kodi, Plex and Emby as media servers. The AC-4 codec is not available on Kodi and Plex, so there is no audio on ATSC 3.0 playback. I eventually went with Emby, which works well and does play ATSC 3.0 audio from the NextGen TV channels. I installed the Emby server software in Windows on a CTONE mini PC (available from Amazon) and this makes for a much more user-friendly setup. The mini PC has low power consumption, so it can run 24/7 at lower cost than a traditional laptop or desktop. Recorded content can be copied treating the mini PC as a network device, and edited if desired (e.g., to make a personal copy of a major movie that may be broadcast only on rare occasions). Overall, this is a great tuner, best used with a third-party interface. ... show more
