I didn't notice this at all in iTunes, but my DVD Player app is killing 
me... it looks like someone shoved a ducker on it, with the longest 
release time known to man... it's making my mobile DVD viewing 
experience a complete pain, especially with music titles! I am watching 
Peter Gabriel's "Secret World" and it freaking me off; as soon as Manu 
Katché hits the kick, the level goes down for a few bars, until it 
rises again, just to go down again on the next strong beat!
Has anyone had this problem? I don't think it is the audio encoding, 
I've tried Dolby 2.0 and Dolby 5.1 and the results are the same (no 
linear PCM on this DVD...).

TIA,

Filipe
