I just hooked up my VSX 81 and everything seems great however now I popped in a sd dvd and the picture looked fine it just was not properly sized to my TV screen. I had to switch my TV to adjust the screen size. When hooked directly to the TV with component I didn't need to do this. Does anyone know anything about this? I can't seem to see any adjustments for video output on the receiver as to TV size or ability. Thanx
