The reason we need the information is so we can tell which programs to recommend. If they are already dvd-video, it would mean one group of programs.
If they are video files in another format, I would recommend other tools.
I’m about to leave, so I’ll just lay out some tools to use. If the videos are already in dvd-video format, with Video_TS folders, then you can adjust their size to fit a dvdr with DVDShrink and burn to a disk with Nero. You can find DVDShrink and guides to using it at www.mrbass.org
If they are other formats, then you need to convert to dvd-video using AVStoDVD or DVDFlick. Both of these are free to download and use. Their output will be a dvd-video the correct size to fit a single layer dvd (default settings), which you can then burn to disk.
Google will tell you where to download AVStoDVD and DVDFlick.
Edit: Ok, you will want to convert this file you just posted if you want it to play in every dvd standalone player. As I said, DVDFlick or AVStoDVD should work for you.
