depends.. do you have a DVD decoder card or a video card that has built-in DVD decoding? if so, use the program associated with it (the ATI prog SG mentioned, Creative's package, etc.) otherwise, i highly recommend PowerDVD. smooth app, never had a problem with it here.
if you're not sure if your video card supports DVD decoding, post what you've got here and we'll let you know. i tried accessing your rig but the link doesn't seem to work.
