I'm trying to backup a foreign made-for-TV movie/series DVD (Chinese/HK). The source material is 29.976fps, NTSC, interlaced. I ran the DVD2AVI-created .d2v file in TMPG to preview and found that in high action/motion scenes, that most, if not all, of the frames were 'combed'..

I've only encountered one other interlaced video where preview revealed that for every 3 progressive frames, there were 2 interlaced/combed frames and therefore, applied the following script:

telecide(order=1,guide=1).decimate(5)

But since 'all' frames during high action/motion scenes were 'combed', what should my 'telecide' line in my Avisynth script be?

mpeg2source("c:\path to .d2v")
lanczosresize(720,480)
assumefps(23.976)
telecide(order=?,guide=?).decimate(??)

or can i go directly to 29.976fps:

mpeg2source("c:\path to .d2v")
lanczosresize(720,480)
assumefps(29.976)

?? Thanks.
