hmm, i've been workin on this a bit and can't seem to figure it out. when i play dvds recently on my computer, the audio for the actor's voices doesn't play, but the background music does. i reinstalled my codecs, and have tried on both windows media player classic as well as 9.0 or 10.0. whatever the regular windows media player is. same in both cases never had this problem before. plays music and avi movies just fine.
