Or try bob, but with a slight speed adjustment (M key then left/right
arrows during playback).  I see the bouncing at standard speed playback,
but at x1.05 or x0.95, the bouncing is gone.

This is with myth from a few weeks back, on an NVidia GeForce2 MX, using
the binary NVidia driver 1.0.7667.

I haven't made time to look for the cause, as I can watch playback at
x1.1 or x1.2 for most programmes fairly easily.
