I've been a Channels DVR user with AppleTV for over a month now and it's performed very well. I love the feature the automatic commercial skip.
Suddenly, on a commercial break, the television went black and stayed black for a long time (estimate about 90 seconds). Then the commercial was over and channels started playing the content normally. This behavior continued for the next show we watched until I turned it off.
It also stuck when I tried the 30 second advance during a blackout. It stayed stuck if I closed the app and reopened it and selected watch. Also, I note that the "commercial skip" note in the upper right was not displaying and screen was indeed black as in no signal (although the Sony TV did not display a signal loss notice.)
I started a show again and when it stuck again on a comskip, I opened my iPad and tried it at the same time frame (love that sync feature) and it skipped the commercial fine on my iPad.
I closed the app and checked the dvr and everything appeared normal including all the logs I could find. I went looking in the forum and found this link:
So, I deleted the channels app on the appletv and downloaded again and it's back to normal. But for how long? Why? Anything else I can do to help diagnose a fix? It's annoying behavior from an otherwise well-conceived app.
