Hi Friends, I purchased Prometheus HD from iTunes. Connected my laptop to Denon AVR-> Panasonc Plasma. Now HD video plays flawless when audio is Stereo track, when I change that to 5.1, video just got Freezes there and no playback of Video and Audio. Same thing is fine with VLC Player. I can play 5.1 Audio with VLC. Any Idea what could be wrong? Thanks.
