I have a Yamaha C900 and got the matrix. The movie pixalates and loses sound a various parts through the dvd. It always happens in the same places. One is at the very begining when the girl fights the cops and when neo and morphious fight. I exchanged my dvd and still no problems. I have two freinds that own the sony 700dvd player and they had no problems playing my dvd. I also hooked up my old panasonic 110 and it works flawlessly on that one. I took my dvd player back to the store hoping that there was just a deffect in the player and I could exchange it but the other three yamaha c900 that they had in the store all did the same thing.
