Sound's fine. It's just the AVI that's jerky. It's a bit hard to explain. I don't have problems with anything else, just this AVI, but the other computer plays it fine.

To try to explain it: It kinda looks like it's flashing and skipping from frame 1 to frame 3 and skipping one in between. It's like a cruddy old cartoon where if a cat was walking from one side of the road to the other. You'd see the cat stand up, then suddenly it's a quarter of the way across then all of a sudden it's on the footpath on the other side. You don't see the whole action, it just goes from point a to point c and skips point b in the middle.

It's kinda perplexing. I'm assuming the computer just needs to be replaced but someone out there might have the magic key that lets me solve the problem considering I can't really afford a new machine.
