I just burned a DVD with Pinnacle Expression from an MPEG 2 file recorded from ATI AIW card. Everything went smoothly except that the video would start to get these very brief pauses. They're like a tick every second. Almost like a video effect. But the original file is perfectly fine. So I know the problem started after that.

My machine has a Gigabyte 8Knxp (Intel 875) mobo, w/ P4 2.6(800FSB), 1Gb Dual DDR, ATI All In Wonder 9600 Pro. The file sits on a Seagate 120G SATA HD.

Thank you for your input.
