I bought the DVD now :) still haven't watched the movie. You were most certainly correct that speedup is present (the video is 25p from appaerantly 24p film). The source doesn't look too bad, and "srestore" in avisynth fixes all the probs in one hit without any issues that I saw in vDub. Also, it appears to me the effects are in 24p not 30p, from what little i could tell in vDub, and looking though the part of DrWho walking through the window it looked fine. Hopefully I can encode it soon and watch it!
I did notice some minor combing in areas where the fields were out of sync, so post-processing wouldn't be a bad idea.
For a pure, "unfiltered" video:
# Fix field errors
Yadif(Order=0,Mode=1)
srestore(Frate=25,speed=1)
AssumeFPS(23.976) # Or just use AssumeFPS(24)
# Crop side borders, and resize vertically (4:3 mod16)
crop(10,2,-6,-2)
Spline36Resize(704,528)
Just going to decide upon what post-processing to use before I encode it.
BTW: to reiterate, if their source is a 30i telecine NTSC tape, they *should* have, *easily* gone to it and IVTC'd it properly, it's so bleatingly easy!
