I have Time warner digital cable with the picture going to my RPTV via the DVI input. Digital and HD channels are centered perfectly but when I flip the channels down into the analog channel range the picture is off-center to the left. This leaves a vertical black bar about 2" wide on the right of the screen and cuts off part of the picture on the left of the screen. I've flipped through the menus on my cable box to see if there's an adjustment, and there isn't any. The user menu for the RPTV doesn't have any adjustment for this either (that I can find). Can anyone help me out? Thanks!
