Notes on burning a DVD using Linux

I can't believe I haven't done this before. I guess my desktop has always had a burner and a gui program to do this. Anyway after searching and finding some links, I'm making some notes for next time.

TITLE="012345678901234"
SOURCE_DIR="/path/to/files"
mkisofs -v -A $TITLE -V $TITLE -J -r -o dvd.iso $SOURCE_DIR
eject -t dvd
cdrecord -scanbus dev=ATA # find your DVD burner in the list
cdrecord -v dev=ATA:1,1,0 driveropts=burnfree -dao dvd.iso
eject dvd

I'm sure there's better ways to do this, but it worked pretty well for the first attempt.
