	Did you mean 23.97 (NTSC 3:2 pulldown converted FILM) fps?    That
	is rather uncommon - most material I have seen is 29.97fps.

	NTSC video is 29.97 (30000/1001 actually ;))

	I've done quite a bit of conversion from MPEG2 to DIVX (using the
	mpeg4ip.sourceforge.net divx encoder) and it's not too hard (slow
	though ;))

	I have taken NTSC (29.97fps) video (movies from www.archive.org for
	example) and converted to Divx (divxenc).  If that is what you want to
	do I believe I can help with pointers to the tools you'll need and
	some sample scripts that I use as templates.

	Oh, are you trying to convert from NTSC to PAL frame rates?

	That I do not know how to do - I believe it requires some very
	expensive equipment.   Also the audio needs to be converted and
	I am not sure that can be done easily without altering the pitch.
