Yes; but to me kerndeint looks like a mishmash of linear and nonlinear 
filtering, not motion compensation. I will have a look at dscaler and 
see what they are doing.

If I were going to roll my own, where's a good place to get blockwise 
motion estimation code in the mencoder codebase? libavcodec/motion_est.c?
