This is a quick compile of DVD Author 0.7.0 and has not been extensively tested.

Requires a copy of libc064.dll which can currently be downloaded from ftp://ftp.netlabs.org/pub/gcc/libc-0.6.4-csd4.zip

I've used ffmpeg successfully to convert video to dvd format, then write to DVD as follows:
ffmpeg -i <inputfile.ext> -target dvd outputfile.mpg
dvdauthor -o <outputdir> outputfile.mpg
dvdauthor -T -o <outputdir>

cd <outputdir>
mkisofs2 -dvdvideo -o image.iso -r .
dvddao image.iso

ffmpeg is available from: http://hobbes.nmsu.edu/h-search.php?key=ffmpeg&pushbutton=Search
mkisofs2 is available from: http://hobbes.nmsu.edu/h-search.php?key=cdrtools2&pushbutton=Search
