I never noticed this on my last hp laptop but my new dell almost everything in itunes plays with the audio out of sync with the video. most noticeable on podcasts. my dell is not high end but it has duel core amd 64 4400 chips 2 gigs of ram. running xp. it has a built in nvidia geforce 6150l video card with a built in sound card. it has done this since I got it a month ago. it is not an issue playing dvd's in windows media player. just itunes. any clues?
