hmmm I think I have hit a snag...
In PAL high res mode the TV doesnt display the bottom 56 vertical lines.
Windows disappear from the bottom of the screen. Games like Banshee and Arcade Pool (plus loads more I am sure) are missing the bottom part of the screen.
Doesnt seem to be a workaround on the TV menu either. Just Horiz and Vert position which helps but is a pain to adjust.
