I spent a few days a little while ago figuring out the best route.
after trying the tovid scripts and getting nothing but out of A/V sync
vob's I figured out the following command for ffmpeg: (this was after
running the ".nuv" through ProjectX in TS mode.
ffmpeg -i INFILE.ts -target dvd -hq -b 4656 -s 720x410 -padtop 34
-padbottom 36 -padcolor 000000 -acodec copy OYTU_FILE.mpg
maybe it was the square pixel thing, but with out the padding the
resulting dvd when played back on a 4:3 tv was squashed horizontally
instead of letterboxed, so I added the letterbox manually.
