I need help buying my first DVD player. I am looking at a changer at around $300 to $400 CDN that plays mp3’s. I am considering either the Panasonic DVD-CV52 or the Sony DVP-C615. I’ll be using composite video inputs (TV sucks) so progressive scan isn’t needed. Does anybody have any suggestions or comments about the two players mentioned? The player will be hooked up to a Sony STR-DE975 receiver.
