I would recommend you look into the Oppo BDP 83. There are a ton of reviews on the web. I am surprised that no one has mentioned this yet. Its probably the best DVD player (superb upconversion) for the price. Yet, it is also a bluray/SACD/DVD-A player. It does bitstream DTS-MA and Dolby Ditital HD via HDMI, all for $499 brand new direct. I currently have the unit hooked up to my Onkyo PR SC886 and it is a great match.
Good luck,
Kenobi
