Something weird is happening, and it's probably something real simple/basic, but I'm a newbie, so please forgive the ignorance. When I press in the button for "progressive output" on the Panny RP56, the TV is only showing it in 4:3 mode...so what I end up with is grey bars on the side (to get 4:3), then black bars on the top and bottom within that (to get the widescreen look). If I depress the button again to turn off progressive scan, it goes to widescreen. It's happening on Gladiator. My TV is Sony KP-57HW40 HDTV. I think it worked fine before, so I must've changed something. Please help! thanks.
