Why doesn DVD playback work in Vista?!
I’ve been wondering the same thing for some time now. The two major issues left to address in Vista are DVD playback and audio control. I have no idea why DVD’s don’t play in Vista, especially since they play fine in WMP in Vista, but the error you get when you try to play them in Vista is ugly. The Centrafuse folks figured out how to fix it, I would hope SD folks can. The other thing is audio… Vista’s sound engine is completely redesigned from XP. Some audio functions of SD will behave normally in Vista, but most won’t. The SD people have said they are not placing high priorities on Vista. That was several months ago though, so hopefully it’s closer to the top of their list. Anyway, the original poster’s issue is with XP, so I’m actually straying from topic here.
