Hmm seems to me Everyone knows how to FAVORITE a CHANNEL.
Now all that needs to be done, to get your guide Favorites to show back up on the menu. Just go left on the remote, to the channel description. Press the STAR button, AND start FAVORITING your channels again. Now the favorite channel option will appear. Like magic.
I hope this helps solve some channel problems.
I've just explained how to fix this issue in easy to explain terms.
If anyone knows an easyer way, please post it here.
