Any one else with directv having problems manually changing transponders on a given satellite? Ocassionally I will get a channel that starts pixelizing and I check the strength meter and fine it at about 25 which is not good. I then go and look and find its say on transponder 10, and I change it to one that gets me back up into the 90s strength meter wise. As soon as I back out of the change screen and back to the program channel it changes back to where it was at. Never had this happen before used to save the best transponder you chose. I wonder if they locked it up on the last software upgrade or what. This is the first problem I have ever had with this unit. It has been very good to me for the last 4 years or so. Thanks.
