I have the same problem on 9600GT. This bug is triggered if the video framerate is close to display refresh rate. It doesn't need to be 24Hz - this happens with 50/60Hz too (with 50/60fps video).
Even with lower frame rates and no CPU hogging Xv loses a frame every now and then.
OpenGL output works for me, although I would rather use Xv.
edit: a 60fps clip which triggers the problem can be found here
