You need to transcode the crapy mpg-files first into DVD-Video-Files (Vobs) - this you can do with tmpgenc - than use vobedit for the creating of DVD-compliant DVD-folder-structures

Than you can burn mpg-files as Video-DVD, which wouldn't make a sense at all, cos' you are losing a lot of quality again when you re-encode the files, in other words - it's shit.
