Real issues with the NBCU channels. Screen comes up and says sorry but there are problems. I've deleted and readded channels multiple times.
When removing/reinstalling, did you restart your Roku before adding the channel back in? By restarting, you're making sure all vestiges of the former installation are cleared from memory and so must be reloaded from scratch.
I am having a similar problem. USA live will list what’s playing but when you click on the channel it won’t load. And NBC will not play the local channel, it says “program information unavailable”.
Thanks for the post.
For more information about that channel's features and functionality, you'll want to contact the channel provider support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
Thanks,
Danny
