One thing you need to be aware of with the 563 is that it needs a firmware update to be compatible with several newer DVD-A. Audioasylum has a bunch of threads on this. Do a search for "Pioneer 563".

I have one that wouldn't play "Goodbye Yellow Brick Road" no matter what I did. You'll need to call Pioneer and get an authorization for the update, take it to a service center or ship it to Pioneer. Once I got the update done it worked fine.
