With just one HDD (if that's what you have), a possible contibutory factor is disk fragmentation.

Better to have a separate HDD for video, preview files etc, or to partition a single disk, to keep the frequent operating system file activity away from video files.

In any event, if you haven;t done so recently, try a defrag.

I have figured it out, it runs just fine till around 2 min 30 sec into ANY video then it gets REALLY choppy. i havent degragged, and my hdd have been recently making wierd noises
