You are stuck with zoom scaling....very frustrating.....Here in San Diego some stations are starting upconvert everythign (even commercials) so that the screen is filled.......Just a side effect of the transition to HD.
I'm Not an engineer, but I play one on TV. My handle is Tweety but I have nothing to do with the organization of similar name. I just had a really big head as a child so folks called me tweety bird.
