I have a DVD-A player, but I can't find the remote for it, so I have to listen to the default layer, whatever it is.
Also, I only have a couple DVD-A's: Queen's A Night at the Opera, Philip Glass, Koyaanisqatsi, Porcupine Tree, In Absentia and the recently obtained Deadwing, Blue Man Group, Audio and...uh...one more.
I do, however, have quite a few "DAD's" from Classic Records, Arts Music (.de) and Chesky.
