But the signal coming from a VCR (an NTSC one at least) is already 29.97 interlaced, either because it's a real 29.97 source or because it was a 23.976 source that was telecined before it was even put on VHS. Either way, the DV camera receives a 29.97 signal that appears to be interlaced so it doesn't have to do any conversion.
It's similar to using DVD2AVI -- all NTSC DVDs are 29.97fps (just like all NTSC video tapes), so DVD2AVI has to decide whether its telecined, interlaced, or progressive video and sometimes gets it wrong...
I don't know how it would work for PAL. If the camera is able to read the signal at all it will probably look something like the output of the ConvertFPS() function in AviSynth -- part of the previous frame will be captured along with the current frame since the framerates don't match. But if you try it I wouldn't mind hearing what it actually looks like
