Attached log, first DVD playback is manual disk insert, second is with Play disk (disk already inserted).
BTW have tried 3 different DVDs all the same result.
Same problem with Titan skin. see attached screenshot, shows what it looks like a bit better, also noticed that whole screen flashes black before showing the corruption and at least in the case of manually inserting the disc, my remote looses focus and I have to click the mouse on screen to re-establish control and I guess that is more of a problem than the screen going funny for a few seconds.
