Advertisements I have three Tivo Stream 4Ks and on my oldest one the HDHomeRun and Channels DVR apps stopped working. The other two Tivo streams work fine. On the Channels DVR app whenever I tried to watch a live OTA broadcast station the audio would play but the screen would start refreshing a full screen of different colors/garbage. The HDHomerun would sometimes do the same or just play the audio from the broadcast. After swapping out one of the other Tivo Streams, I determine that it was only a problem with one of the Stream 4ks. I also reset the problematic Stream 4k to the factory defaults and had trouble where it locked up in the setup process a few times. When I finally got it back up then I found a setting in the Channels DVR app for the video player that was called decoder and I set to 'Software' instead of the default 'Hardware' and then I could see the video just fine. I changed it back to 'Hardware' and it messed up again. There is no way to change the decoder on the HDhomerun app. I am certain there is something wrong with the Stream 4k. A wrote up a support ticket at Tivo describing my problem. Then a day later or so the ticket was closed and resolved by Tivo by sending me a massage that I should go to their support page and go through their troubleshooting steps. So I check the ticket status and sure enough the ticket is closed. So then I call them on the phone and after spending a bunch time while they insisted that I should unhook my ethernet connection and use wifi instead -- which I did. They also wanted to blame my setup/TV/Denon Receiver. I kept say over and over that I have three of these and the other two work just fine. Finally They said the would open up another ticket and refer the problem up the line. That was five days ago. Not a very happy customer.
