I bught my 57" sony yesterday. I went through the manual, but certain things are not very clear. Here are my connections. I run a Component from my AVR7200 to Video5 of 57WS510. I run a Component from my Digital HD Cable Box to my 57WS510 (inorder to liten to the TV through its speakers and not keep my AVR on all the time I watch TV). I run a Video Cable (Yellow RCA) from my AVR to TV (in order to activate the OSD menu.. Ofcourse, I can remove it later - not that I configure it all the time. Now the question I have is, all the HD signals that my TWC receives fine. AWESOME pictures! But when I watch the other 4:3 digital transmission or regular transmission like USA, TNT, TBS etc... I am not able to zoom the picture to avoid the burn. When I watch a DVD (connected through my AVR component and Optical Audio), I am able to play around with the size of the 4:3. Shouldn't I be able to zoom even the regular cable channels that I receive through my HD digital Cable Box? Anyone who owns 57WS510 can even PM me.
