..strange thing.. everything was working, but now the screen goes black when trying to play any videofile(incl DVD)..
If i pause or access meny during play the video will show, but as soon as I unpause or the menu disaperes(timeout) the screen goes blck again... don't think i (intensionaly) did anything to the settings...but guess i did.. cant seem to find out what.. :S

Try running the AVWizard again, it sounds like the transparancy got disabled.
