Film/video mix with incorrect pulldown flags

[Not sure if I got the right forum, but I suspect the answer will involve avisynth.]

I'm about to backup Buffy seasons 4-7 R1/NTSC. They seem to be a mix of NTSC video (maybe 10-20%%) and telecined film (the rest). A person who is usually sane and reliable assures me that there are some incorrect pulldown flags in the film sections.

I'm thinking that the "no prisoners" way to process these would be DGIndex ignoring pulldown flags, then use the two pass TITVC filter that detects duplicates and writes a timecodes file, finally muxing into variable framerate Matroska. [This worked great on NTSC X-Files, which are similar. But it does mean chapters stop working.]

Do you folks think I'm right, or is there a better/simpler way of doing this?

Well, if indeed it is video you have there mixed with film (I had a post around here in which I asked something similar) than vfr is the most easy and good method (and using TIVTC for vfr is quite easy). Of course in case the timecodes say 100% film like it happened to me it means hard telecine (therefore not detected by dgindex) and in that case a normal IVTC will work nicely. (you can also check manualy some parts after saving a d2v file with honor pulldown flags to see what pattern you have, if it's not 3:2 than give TIVTC with vfr a try to see what it sais).
