I don't have anything written up, I just do it by hand each time. I know, 
kinda old-school, but I've been using CLI for decades.

Basically, here's what I do (from memory)...

1. Copy the captured nuv file to my main machine
2. Use avidemux2 to cut the nuv into .m2v and .mp2 segments (this is just to 
remove commercials, otherwise I just demux the whole thing with tcextract)
3. Shrink each .m2v file with tcrequant as desired
4. Mux the elements together with "mplex -f 8 -V" to get a set of .mpg files
5. Feed those files to dvdauthor to generate a DVD structure
6. Build a DVD ISO image with mkisofs
7. Burn to plastic with cdrecord-prodvd.
