I've been looking at players quite a bit now, and have noticed in some eBay ads that feature Sony marketing papers that some players are spec'd to produce 50 or 51 dB of video S/N. Based on that spec alone, if true, they would compare to some of the better/best players on the market. What keeps these from being great players? What I do know - No AC-3 out is one handicap, I have yet to see a Sony player with one. And the funky door mechs on some models. Besides that, what're the drawbacks? Thanks for any replies - - CM For the record, I have an MDP-333 (Bad door), a CLD-D406 and an RCA LDR310. No experience with the first 2 yet...sitting on the shelf.
