Well, I do entirely misunderstand this, so thats why I came here. I 
wasn't sure what all the different encoding options for both audio and 
video were for. That, and theres tons of different programs, mencoder, 
mjpegtools, transcode, encode2mpeg. I've heard of transcode, but haven't 
tried it yet. I wanted to encode directly to a VCD format in the first 
place, but I ended up with the DivX files...

I ran sh divx2svcd, but it gives me an error:
================================
[andrew at localhost TOOLS]$ sh divx2svcd
DivX2SvcD 0.5.1 (C) 2003-2004 Vajna Miklos
 
ERROR: Can't find any sutable mplex utility. You can download
tcmplex-panteltje at http://sunsite.rediris.es/
sites2/ibiblio.org/linux/apps/video/tcmplex-panteltje-0.3.tgz
[andrew at localhost TOOLS]$
================================

I will try downloading mplex, but then what do I do next?
