Been having issues with tennis channel. Looked on their website and the feed seems to work. When trying to record on stable dvr software getting "unsupported protocol list". Upgraded to 11.1 prerelease, and now getting this. It does seem to record for a few minutes sometimes before it conks out.

It did when I looked a few minutes ago.
I had the same issue this week end on ESPN. I stop the app on my device and opened it again the error did not occur again.
