Maybe you can try using ffmpeg to convert the DivX to MPEG. ffmpeg will
produce a non VCD-compliant MPEG stream which you can then make
compliant using a combination of mpgtx (to demultiplex or split the MPEG
into its component audio and video) and mjpegtools (to multiplex it
back). Finally you use VCDImager on the re-multiplexed MPEG stream. No
editing required, just convert, convert, convert. Maybe you can even use
mplayer to convert the DivX into some sort of weird MPEG format.
But I'm just wondering, why convert a DivX movie to VCD? DivX has a
higher compression ratio (since VCD's tend to have more stringent bitate
requirements). You'll notice the difference only in high-motion scenes,
something quite unlikely with your wedding video. Of course, MPEG is
freer than DivX (but then you have OpenDivX and xvid).
