I really don't remember a default guide setting on my 722k. I only remember being able to choose which guide to use at the time, and that it would open the last-used one the next time I opened it.Yes indeed we did.Besides the 4 favorites lists we had all channels,all sub,hd only or however it was worded then.I prefer the all channels list,lock out what channels you don't want and a nice dark blue guide to boot.
But, hopefully they'll restore that forgotten-by-me setting in the menu soon.
