My new AIW9800 SE soft-modded to PRO seems to have trouble running DVD's and some video files. On video files there are small black dots flickering about the screen, and when playing DVD's it gets past the opening blue copyright info screen then promptly goes blank, although sound is still there. I'm sure it's not a result of the soft-mod, as games run perfectly fine with no artifacts, and I can't see the DVD player putting any strain on the extra 4-pipelines. Anyone got any ideas?😕
