I didn't find a clear answer to this from searching the forum. I'm hoping someone can post a solution... I used the joystick/stop trick to center the picture on my 16:9 TV using the Avia overscan pattern. However, when I play a 4:3 DVD, the picture is shifted a few notches to the right. What gives?! Now, if I center the 4:3 image, then the Avia overscan pattern is a few notches off to the left. Is there a way to fix this? BTW, my RP91 is in U4/Auto2/Auto mode. This brings me to another problem. Each time I power off & power on, the player reverts to U1 mode. How do I get it to stick to U4/Auto2/Auto mode? Thanks in advance for any help.
