Good to see the poster get his channel back! For his channel info, he can always go to titantv and set up a personal channel guide, its easy once you figure it out.
Still have 2 of those GI receivers , a 550 and a 650, dish-movers mostly now. If they are switching polarities on him when he turns them off=its probably because the analog boxes, some of them anyway, were wired to search for a videocipher signal , once the box was turned off. If f they weren't on a scrambled channel-the reciever would search for a scrambled signal to keep the box authorized for pay programming. Back when they made it available to us, that is.
