I have setup my Panasonic 5 series plasma with tha AVIA disc and for DVD playback it looks fantastic. However I set up my PC input (Normally Sky input) using the disc and I am not so sure the picture is better when viewing Sky pictures. The biggest problem seems to be when you lower the sharpness levels to that recommended by the AVIA disc then switch back to Sky viewing. The setup disc recommends viewing the new settings for a week to allow your eyes to adjust. Anyone suggest optimal sharpness levels for Sky viewing?
