Griff; could you expand on this a bit further? What precisely did you change? I have the exact same problem with a P42G25 I just got yesterday (using Comcast and the identical STB). I thought it was the TV and was all set to bring it back, but based upon what you're saying I might be able to simply adjust the STB and be done with it.Quote:

I callied Panasonic and the tech I spoke to was familiar with this issue. It has something to do with Motorola cable box supplied by Comcast. She had me go into the secret "user setup" menu in the cable box (menu appears on a white screen on the TV) and change the 4:3 override and the Additional HDMI settings. If you have this issue, call Panasonic. So far, the solution seems to work.
