Hi, when i play DVD's on my pc the video is fine but the audio stutters really bad and i am not sure why but my guess that its a driver issue...i got a 6 channel soundcard with the latest drivers C-Media Wave..So I uninstalled the soundcard and went to my bios and turned my onboard audio on and played a dvd with my onboard it worked fine..but i need my soundcard because i can only use 2/5 speakers without it..
