Query: Good tunes, odd recording

First, don't assume you can play this back on your computer, because the copy protection will get in the way and make the sound simply awful. Think back to the old VHS copy protection where the screen and volume would go up and down wildly, and you've nailed it. I was very disappointed that an original DVD chosen for its higher audio quality would act this way. It had to be played from a cheap hardware DVD player, and then the audio sounded a bit funny since I don't have 5.1 stereo. It's probably great if you have a surround-sound setup; otherwise, pass on to the regular CDs. Also, the music has been remastered and in some cases changed more than one might think, sometimes for the better, and equally often for the worse. I never thought I'd say this, but I recommend getting the "lower quality" CD - it'll sound better.
