I was getting some of the errors over the weekend related to DirecTV that were mentioned in another thread. However, ESPN never returned so I deleted and re-added DirecTV as my TVE source. Now, ESPN/ESPN2 etc. aren't even listed. I don't know if this is related, but I logged into DirecTV's own website to see if I could stream ESPN from there, and ESPN isn't listed either (though I don't know if this is a valid test because I rarely use DirecTV's site.) Is ESPN still working for anyone else with DirecTV as your TVE source?
Can you login and watch here Watch ESPN: Online Live Sports, Replays, Highlights with your DirecTV credentials?
If you can, then Individually rescan channels with issues using Rescan Channels under the gear dropdown next to your source in the DVR web UI
So do you have errors or checkmarks next to your channels?
If errors, did rescanning the individual channels with errors fix it?
Hmmm. it seems to have gone away on its own. I guess false alarm.
Could be your DVR just auto updated to the new release version and that fixed it
