NTSC movie, fps = 29.97, interlaced, what do I do ?

Hi all, I live in a PAL country and this is my first NTSC movie to back up I have backup many PAL movies using CCE/scenarist, etc... without any problem but I have read so many information about NTSC especially the fps that I don't know where to start If I look at DVD2AVI guide, it says that if the frame rate is 29.97 and and the video type is NTSC then I need to do an IVTC. Do I have to do it and if so how ? I have never used Avisynth but always VFAPI Also what do I have to do with the interlaced frame type? I have read somewhere on the net that pure NTSC can not be IVTC'd ? So what I am trying now is using DVD2AVI with field checked to none If there is anybody out there that could help me, that would be much appreciated (also don't tell me to read the guides because this is what I have been doing for the past 2 hours ):) Thanks

What is the movie? It probably was originally FILM, so use FORCE FILM option in DVD2AVI. But always TEST this assumption by creating a .AVS script and running your video through VirtualDub. If it is truly film (and I suspect that it is), then the above will give you a 23.976fps (24fps) sequence that you can then convert to PAL by your favorite method.

Let me say this again, in case you missed it the first time. Use the FORCE FILM option in DVD2AVI, then TEST the assumption that the film is FILM by creating a .AVS script and running your video through VirtualDub. Don't use DVD2AVI to view your video - it only shows KEY frames. What is the name of your film?

I worked on lot of DVD9 which are NTSC Interlaced 29.976 The source for these DVD9 are Film (the movies we see in theatre but shot in India and I hope Film has not NTSC or PAL). When I preview in DVD2AVI, they are interlaced but not the whole picture frame. Interlacing is appearing mostly only in areas where there is motion. The question is can I apply Force Film on these? Force Film gave me skipped frames (jerky video or missing frames) when I tried a year back. I might be Stupid, if the Force Film works on these as I always did Decomb.dll Telecide().Decimate(cycle=5) to recover progressive frame which looses quality as I did not set post=false. Anyone expertise in this Interace mode? TIA

Easiest solution would be to use Doitfast4u and Avisynth. Doitfast4u will run your video through DVD2AVI and create an AVS script for your video.
