Best way to deinterlace jagged progressive video?

[panda-34]

I've got quite a bunch of mpeg-2 dvd material which was made from progressive source (film) by interlaced scan. So, probably because of mechanical jitter, odd lines are shifted against even lines by small amount, like maybe 1.5 pixels. I wonder, what's the best way to make a pure progressive out of this mess? Interpolating deinterlacers don't do their job (lines remain jagged), blending helps but blurs the picture too much. Yadif removes jaggedness completely but makes awful mess from horizontal edges.
Maybe there's some filter that can simply shift fields against each other until vertical lines are straight?

Can you post a video sample cut and demuxed (to MPEG-2 ES, or M2V) from one of the relevant VOB files with DGIndex? That will allow people to experiment with various solutions.

By the way, shifting is not uniform both vertically and horizontally, so it has to be quite a smart filter to do the job. Guess I'll have to stick with linear blend.

Have you tried QGMTC or GMTC_beta2? It's very good at stabalising interlaced stuff ...
