I hooked up my Mac Mini to my new LCD screen today via DVI and ran into a problem in Front Row. Hangling through the menus works fine, album artwork gets displayed properly and floats around, but I get no video output - neither from the videos I added manually nor from the trailer section in Front Row. I can hear the sound playing, but there is no image. I tried several different resolutions, but to no avail so far. Watching DVDs works fine, as does playing videos in iTunes and switching to full screen from there - but Front Row leaves me down.  DVD playback from within Front Row doesn't work either, but as I wrote it works fine otherwise.
