OHHH, you mean that "bounce"... I thought you meant jerky frames. No, THAT bounce was already on Zion's capture. If you look closely, you see that the image doesn't just shift, it literally "waves" like a flag (in frame 302 the lower part of the image moves to the left, and in frame 303 the upper part follows... looks like some analogue error... old videotapes sometimes show this artifact). I am not sure if this is already on the laserdisc, or if it occured during capturing.
