When my Bolt died and Tivo refused to sell me a replacement (because they no longer service Canada) I was forced into looking for an alternative OTA solution. I looked at the HomeRun setup but even though I'm a techie by trade and nature decided that the benefits it offered compared with a Tablo just weren't worth the extra hassle.If you want an OTA DVR, you're better off looking at an HD HomeRun tuner (either ATSC 1.0 or 3.0) paired with a computer running either Channels DVR or Plex DVR. Either way, you'd watch live and recorded TV via the Channels or Plex app on Apple TV, Android TV and/or Fire TV. (The Plex app supports additional platforms too, like Roku and various smart TVs.)
If that's all too complicated, have a look at Tablo.
Started with a really cheap 2-tuner refurb Tablo and was so happy with it I replaced it with a 4 tuner model. Very pleased it and being able to use any size hard drive is a real plus. Remote access and control also works really well.
