Video stutter

I've ripped a couple of DVDs to 1GB avi files to play back on a core duo Mac Mini, 1GB RAM, 80GB free hard disk space. However, the files don't play back smoothly, 'glitching' every couple of minutes.

This happens with Quicktime and VLC, although I prefer VLC's settings for playback.

I can partially fix the problem with a restart. Then, free RAM memory creeps to almost zero (from about 600MB) and the problem starts again. For example, I watched an hour of one video (2 hours long) last night without a problem, glitching started, free memory almost gone, restart, all's fine.

I assume this is a lack of RAM, and perhaps an extra 1GB would sort it. Or the memory thing could be coincidence. Or alternative software? I've more or less ruled out the files as a problem because it happens on the three I've tried, occurs at random points, and the files play smoothly when burned to DVD and played back on a standalone DVD player.

Thoughts please? Thanks, Rob.
