I'm in PAL zone, for this reason I don't know enough NTSC format.
My question is:
1 - DVDs at 29.970 fps (telecined), still have original audio, without changes, isn'it? I mean, movie has same playing time as original progressive one?
2 - When I extract this audio from vobs, I can mux it with same video IVTC, without another change?
3 - Could someone send me a sample vob with audio (maybe cutted with dikumciser) of a NTSC 29.970 telecined through https://www.yousendit.com/
Only need to upload the sample and post here the link to download it.
Thanks in advance.

As telecining is a process not just up-pitching the videospeed but inserting doubled frames at certain points incl. phaseshifts ... the movietime therefore will be the same after telecining.

Just a telecide().decimate() ... thats all and no audio speed postprocessing is needed.
