I'm looking for a new DVD player and I'd like it to be a DVD changer. I have a Sony Mini HiFi system that has 5.1 inputs so the DVD player would have to have built in Dolby Digital / DTS decoding w/ 5.1 outputs. Most of the ones that are in my price range which is $200 - $350, have progessive scan, DVD Audio Playback, & MP3 Playback. I'm not so interested in progressive scan but I am interested in it being able to play back DVD+R DVD-R media. Does such DVD player exist?
