Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
The files need to be made using a small list of codecs, both for audio and video. Use mediainfo program to see all of a files specifics. For audio stick with AAC for stereo or AC3 for multitrack (or stereo). For video stick with h.264. There are more, but I find that sticking with these couple, easy to remember, codecs works well.
