I have a Panasonic 50" 60U plasma display. I'm a little confused regarding viewing formats. For Cable box viewing I have to change the aspect every time to have full screen viewing. Is there a way to avoid this annoyance.(cable box settings don't seem to help).

Also wondering about DVD viewing. I have an Oppo upconverting DVD player. Some movies still have black bars top and bottom despite widescreen display. Is widescreen and 16X9 2 different formats.. I use the zoom setting on the display to full screen view but am unsure if that hurts resolution or sharpness.

These are just growing pains with the new equipment but any feedback would be great.
