for the last few months, TV2 on one of our 622s has been completely screwed up. if you bring up "All Channels" in the guide, it only shows hd channels, and the custom guides we had made previously now only have 2 channels (both dish info channels). i am pretty sure it has somehow locked all the sd channels. so i go in to type in my password for the locks and it says i have the wrong password. is there any way to reset just tv2 so that tv1 isnt messed up? if not how do you even reset the 622 period?
