So I upgrade tv's from a 29" standard flat screen to a 32" wide screen lcd. After 24hrs of searching and adjusting to get the picture right I finally figure out how to change the aspect ratio on the R15 but it does nothing to the picture. I have tried this with the TV set to both 16:9 & 4:3 with no difference at all when I change the settings on the D* box. What gives???? Please help!!!!
