I thought so. Hmm, that means the traditional transcode agent mpeg2enc doesn't
support VCD creating then, since VCDs are encoded as MPEG-1. correct? Ref:

**ERROR: [mpeg2enc] Interlaced encoding (-I != 0) is not supported by MPEG-1.

hmm... I read "even non-interlaced video will be written interlaced on the
dvd" [1], now I've confirmed that it is wrong. Progressive 24fps?
interesting, any luck to have burnt such DVD anyone? How did you do that, say
we are converting from a 23.976fps avi? I remember when tried encoding without 
pulldown, I get the following when doing the dvdauth:

not a valid DVD frame rate: 24000.0/1001.0 (NTSC 3:2 pulldown converted FILM)

thanks
