Have you tried VLC player? It does a great job of playing EVERYTHING and even auto-syncs sound to video. This may isolate the possibility that WMP is the issue.
I'm not too familiar with SATA driver control, but do remember in ATA days there was a DMA/PIO setting for the IDE controller that helped tweak speed/buffering issues. Don't know if SATA has similar things or if your DVD drive is SATA or ATA but it may be worth a check.
