Thanks for the post.
Do you have any of the follow channels: Vudu, the Aquatic Life screensaver, or Netflix. If so, have you tried removing these channels, then restarting your device and trying to add channels to see if your issue is resolved?
Please be aware that many channels on Roku are developed and maintained by the channel provider themselves.
