My understanding is that VCD format is not interlaced and hence my question:
Do I need to use a deinterlace filter to convert interlaced DV AVI to VCD or will CRT display and/or DVD player correct for it?
Another question, though unrelated, is do I need to convert BFF DV to TFF, when converting to mpeg2? Is TFF NTSC standard?
Thanks much.

You'll end up deinterlacing one way or another when you resize to VCD spec. Your best bet is to deinterlace before resizing. Use something like VirtualDub's SmartDeinterlace or AVISynth's LeakKernelDeint filters.

re: VCD deinterlacing,
Just giving it the 352x240(288) down size USUALLY does the trick itself (if you're in a hurry), but this isn't optimal.
There are a number of ways to do this. In the past, I've used TMPGEnc and applied their "Odd Field-Adaptation" Deinterlace filter to good effect.
Lately I've been thinking that a good way to go would be to just load the clip in Virtualdub, Apply the "ViewFields" filter (which puts the fields side-by-side), and CROP out the right side (aka 2nd field). Then do a smart resize (horizontal direction only). Not sure if that would improve things (more true to original image) or not...
re: TFF/BFF,
TFF may be the most common, but there really isn't a "standard". It's a requirement for Good, Online-Tape editing, but not for DVD playback (it can take either one--I know, I've sent replicators both kinds and both have been acceptable).

Yes, you can get some jaggies, but the horizontal resize alleviates that some, and sometimes and on some material, I don't want a 2-field blend. It can become TOO soft.
Just trying to throw out different options for users to try and see which they prefer for a given material. It always changes...
