If I understand you, you want to create vcds?
then check out:

I've been using an older version (which was basically a modest script that worked wonders) that is text-only but apparently there's a gui now.
it creates vcds, and can convert just about anything that mplayer can play (which is to say just about any video clip out there). It leaves ~ 700MB chunks by default which K3B can use to create and burn the vcd images.
