SVCD->DVD / Scenarist framerate problem

[mistame]

First of all, yes, I know I can use dvdlab or svcd2dvd to simply use the patching trick on svcd's->dvd's, but lets pretend, for my own reasons, i just want to do a "simple" conversion :). Anyway, my source file is from an NTSC TV svcd, 29.97fps. It seems to be telecined, there's 2 interlaced frames then 3 progressive (although reading all these guides on interlaced and progressive, etc has jumbled my mind so I may not know what i'm talking about). In DVD2AVI the field operation is set to none then I'm using AviSynth -> CCE. Avisynth script:

LoadPlugin("MPEG2Dec3dg.dll")
LoadPlugin("Decomb.dll")
vid=Mpeg2Source("307test.d2v")
aud=WAVSource("307AUDIO.wav")
AudioDub(vid,aud)
Telecide()
Decimate(cycle=5)
ResampleAudio(48000)
Crop(0,66,480,346)
LanczosResize(720,480)
ConvertToYUY2()

The output looks fine with no interlaced frames and is 23.976fps but when loading into Scenarist I get "Error : Frame rate (1 = 24 000+1001(23.976)) is wrong.". At this point I got really lost (as if I wasn't already) and tried using force film in dvd2avi without the telecide and decimate functions in the script, or setting the framerate in cce to 29.97 (video imports properly with this but audio is out of sync) and any other number of newbie shots in the dark. can someone please educate me on what i'm doing wrong? and if i'm leaving out vital info to solving this problem let me know.

If you are encoding to 23.976 fps using CCE, you need Pulldown.exe after encoding to set the Flags correctly.

Thanks for the info. However, the resulting dvd now plays slightly fast, like it's going at 29.97fps and the audio is very out of sync. Opening the final m2v in virtualdub and playing it with the sound in there is fine; no sync or framerate issues :confused:

My Scenarist manual tells me that Scenarist only support 29.97 fps NTSC (Page 42 Preparing video Assets). So why don't you keep 29.97 fps?
