Grey screen in iTunes when playing downloaded movie
Since the update from 10.7.5 Server ed. to 10.9 Mavericks on my Mini-mac I have problems with the playback of downloaded iTunes movies. The only thing I see is a grey screen. This not only is the case for playback with iTunes, but also for playback of DVD's.
When I want to play the movie on my AppleTV (from the iTunes library on the same mini-mac) it's no problem. On my iMac: same. No problem.
So it must be something on the mini that handles the playback of copy-protected material. I think I need to remove something and get it installed anew, probably something Quicktime related.
Is there anyone that can help me out?
