I have a Dell Latitude E6500, and have Windows XP. I can play DVD's just fine with no audio problem. But starting just last week, when I try to play a video clip on an Internet site, eg. NBC, the video played but the audio came through in stacato form like it was missing pieces.Any idea what is going on. Oh, by the way, I have now been on hold at MSN phone support for one hour and 38 minutes!!!!!!!!!!!!
