I just signed back up on Directv after 18 months on Dish. They installed an R22 box on my widescreen HDTV (I didn't sign up for HD service). Every channel has a pillarbox on the side of the picture. Is this a common problem? The installer said he thought it should have cleard itself up with the software download that happened right after start up.I've had two other DVRs connected to this TV in the past, and never had this problem. Directv tech support really offers no help, other than to say they don't know why this would happen or if it can be fixed. My TV's aspect ratio adjustment doesn't help this either.
