Ah, now I did have that with Platoon when I ripped it from youtube - someone more knowledgable than me might know why, but I seem to think that the current AVI code seeks by time to an appropriate frame based on the frame rate, and depending on how many frames there are from the last key frame to that point, it can overshoot or undershoot and generally break up. I didn't use Xvid though, it was some standard MPEg-4 thing that was the same, but not.

I ended up using some MJPEG codec I found in K-Lite to try to force loads of keyframes and it sort of worked, but it still seems a bit choppy even now. I guess it's because AVi isn't meant to do what this is forcing it to.
