I usually leave my guide favorites set to "My HD Channels". Occasionally I go to "All Channels" for browsing. I can change the favorites to "All Channels", but as soon as I re-enter the guide, it goes back to "My HD Channels". This only happens with "All Channels", so I guess I can just start selecting "My Channels", but then what's the purpose of "All Channels" then? (I understand the difference between "All Channels" and "My Channels"). I just don't understand why "All Channels" doesn't stick.
