I don't know, I have never tried to make a vcd, I think they are a waste of time (I'm not interested in sweating to make something at 1/4 dvd resolution). > > Many recent NTSC dvd's are progressive 24fps, but a surprising number of > > NTSC dvd's are interlaced... > > hmm...

I just make everything 30fps. BTW, every 24fps feature I have seen has had a short chunk of 30fps at the very beginning, but I can't see how that could qualify as any sort of "trick", I think it's just that the distribution companies all do their logos at 30fps. By the way, I often see Chinese dvd's where there is a deluxe Hong Kong release at 24fps, and then a bunch of *ahem* other releases that are all at 30fps, and usually one with the interlacing backwards or sideways for good measure. There is also often one dvd that is "recovered" from a vcd that is a total throwaway.
