I've been having issues with movie playback using a large 1080p HDMI TV.   During playback the audio level will come in strong, go faint, then go strong again, but not on any sort of pattern I could discern.   It did this on three seperate movies legally purchased via iTunes.  I get audio and video without trouble, its just the audio goes soft when it shouldn't.

 

If you remember the VHS days and "MACROVISION" encoding, then you have an idea what it was doing, although it was the audio levels, not the video playback.

 

Is this a fault of the system, a DRM gremlin, or something else?
