If you have AVI files:
Convert them to DVD-format http://members.home.nl/thefilmmachine/
and burn http://www.afterdawn.com/guides/archive/burning_dvd_with_nero.cfm

If you have MPEG files:
Convert them to DVD-forrmat with DVDLab PRO or Ulead DVD MovieFactory (I have not find any freeware software to do it)
and burn.
