Anyone know why this is? I figured the field lines would just be doubled in the motion areas and overlayed. Jagabo, was this maybe what you were talking about the YU12 issues?
Yes, that is from VirtualDub's incorrect handling of interlaced YV12.

I've seen TV broadcasts do this when upscaling or downscaling between HD and SD.
My problem in those linked threads was a reversed interlacce, I never ran across the horrible interlace errors seen in your examples. When I have time, I'll share some info on my exact versions of all software involved.
