Ok, so in the middle of watching a show, the screen went green.
In this case, I was using TVE for DirecTV to watch a show on Discovery Channel. I also tried some other channels after this occurred. The green screen still happened on several "Discovery" channels (not all).
I logged into my DirecTV account and was able to watch the channels in question with issue, i.e. no green screen
I tried to rescan some of the individual channels, no difference.
I also tried to reboot everything, including the OS (Windows in my case), no difference.
I'm unable to watch directly from a browser in the ChannelsDVR settings pages. Basically, I get an unsupported format error (this is not new and doesn't seem to matter to the client I normally use to watch/record with).
I tried using VLC to connect and watch one of the channels in question and it also got the green screen.
