I have a 33inch Sanyo TV which is 4.3 ratio. my DVD player is a Panasonic RV32, I have a problem with a few discs which go to black level and a quick return to peak white. this video excursion makes the whole picure very unstable with video clipping the sync. "Zoom" facility which I hate to do! corrects the instability, is the TV too old at 7 years? to be compatible with DVD technology? I have the disc "High Fidelty" which is a disc that exibits this problem.Can anyone help?
