I have a 46" magnovox LCD HD-TV w/ all connections except VGA or DVI. Since upgrading my DSM-520 to firmware 1.05, if I go through setup, using any type of connection on the tv, and change the aspect ratio to 4:3 on the DSM-520, the resulting image on the tv is 16:9 (wide screen.) The opposite is true, if 16:9 is chosen as the aspect ratio on the DSM-520, then the resulting image on the tv is 4:3 (letterbox.) Is anyone else experiencing this issue after upgrade?
