I have a Panasonic TX28 100hz TV and If I connect my DVD player to AV2 the picture quality is a lot poorer than if It goes though AV1. When on AV2 it s like a criss cross pattern is in the background, enough to be noticed but not totally ruin the picture. I've tried every permutation of the settings but nothing seems to work. Is there something different about AV2, is it only meant for particular items. I had this effect on my last Panasonic as well , with other dvd players so I assume the issue is AV2.
