[sclug] create DVD/VCD from multiple .AVI files?

[John Stumbles]

I want to get some stuff from DV camcorder onto shiny round things. I'm 
using dvgrab to automatically split up the DV tape into separate takes, 
so I have a number of .AVI files which I now want to convert to DVD or 
VCD format. ffmpeg would seem the business but it doesn't seems to know 
how to take input from a set of files in this way. Options therefore 
seem to be (a) merge the AVIs, or (b) merge the output files.

avimerge (from transcode) segfaults :-( (Kubuntu 6.01 / AMD64) and I 
haven't found anything that'll merge mpegs.

If I'm making a dvd I guess I should be able to specify multiple files 
in <vob file="filename" ...> in dvdauthor's control file but 
man:dvdauthor is silent on how to do that too <sigh!>

Am I missing something obvious and (hopefully) easy?

Or do I need to take a couple of weeks out to find out how to drive 
mencoder or transcode, if indeed either of these beasts can do the job?
