Hello,I/m running an hp g6 pavillion system with the a6 chipset and 8 gig of memory. it is running windows 7. I'm also using the latest version of itunes. I find that when playing a downloaded (from itunes) movie the video and audio portions of the playback get out of sync. looks like a rerun of kung fu theater from the 70's. I've heard that this is a known bug with amd chips as was wondering if this was true.
