DVDs won't play

[livesteamfan]

Whenever I try to play a dvd in either of my drives the program starts, and then either closes or gives me a send/don't send error message. Both drives will read/write cds and will burn dvds. They also work on a different system. My os is Win xp pro. The computer also freezes every now and then and I sometimes get the bsod.

it has worked before. i recently replaced my motherboard with an asus a8n32-sli deluxe and that is when it stopped working. and what do you mean by dvd decoder? if it's software i wouldn't really know, i'm better with hardware.
