Hi
see reply to your post on mpeg2 to dvd.
Tmpeg enc/ express, Canopus procoder or procoder express can do the encoding . they actually cost a bit bought new but trial versions exist or you may have a friend who will be wiiling to borrow you his/ hers ( LOL)
If you dont have any standalone programs, you can import these files into into a video editing software which will then rencode them for you in making a dvd
Good luck
