Best Avisynth filters for 29.97 interlaced -> 23.976 prog

[absinthecarolinas]

I'm creating an XviD from DVD. The video is a classical music concert, and DVD2AVI reports it as Interlaced, 29.970 fps. You can definitely see the interlacing when examining it in VirtualDub.

So far I'm just using the very simple script of:

Mpeg2Source("myflick.d2v")
FieldDeinterlace(blend=true)
LanczosResize(640,480)

FieldDeinterlace definitely makes a great improvement on the combing effect, and I think I would be happy with this just as it is.

But is there a good combination to, for instance, split fields and combine back into frames, eliminate duplicates, and have a resultant 23.976 fps file? (if I wanted to, say, put the concert on a VCD, for example). I'm sure there's a way to do this, and I've read some documentation and threads at doom9 on such filters as telecide, decimate, and decomb, but it's rather a lot to take in all at once, so I'm wondering if anyone might have some real-world examples on what might work here.
