Thanks for the suggestions -- this worked pretty well. For the record, here were the steps I used: ffmpeg -i program.mpa -ar 48000 -ab 192 -acodec ac3 program.ac3 mplex -f 8 -o program.mpg program.mpv program.ac3 dvdwizard -T 'disc title' -N PAL -A en -t 'program title' -c 900 program.mpg (edit dvdwizard.xml, change aspect="4:3" to aspect="16:9") rm -r dvd && dvdauthor -x dvdwizard.xml Cheers, Andrew
