Ran across this at BB. 7-disc changer with DVD-Audio, Progressive Scan, DD and DTS decoders built-in(which I need because my reciever is only 5.1 ready). Anybody have experience with this unit? How does it compare to the JVC XV723, which is supposed to have superb image quality? Oddly, the JVC website makes no mention of the built-in decoders, but the carton says it has them.
