This is probably a pretty stupid question, but I can't seem to find an answer that applies to my version of MythTV (2:0.25.2). How do I create a Favorites group to filter the channel listings in the EPG? If I go into the EPG and press '/' to change the channel group, nothing happens. If I press '?' to mark a channel as a favorite, I get an error "You don't have any channel groups defined". All of the instructions I can find refer to older versions of Mythtv that have different menu structures. I've seen some instructions on how to do what looks like manual database entries, but it's not at all clear to me how to do that.
