I tried to make a favorites HD only custom 1 guide to easily browse the HD channels and it worked but then I could not get it back to all channels so my wife could browse pay per views, etc. I tried pressing guide several times and menu but could not get "all channels" on guide until I deleted the custom1 option I had set up. Then I got all channels again. I know I can hit guide twice, hit channel down to HD and be in all HD again but it is not convenient. Also thanks to a post here found the back button will get me back in HD guide after selecting a channel but my Harmony remote requires going into another menu to get the back key so it is easier to dig up the other remote. Any advice? Thanks Yes, I know I could teach the Harmony the back key but every time I try to change something it is at least three hours of redoing things.
