Movie Maker has several different versions that are not quite the same depending on which operating system you are using. Though I believe the stand alone version 2.6 can be used in both Vista and Win7.
DVDFlick will convert various types of video into dvd-video, ready to burn to a disk and play in any stand alone player. It has no editing functions however, so if you need to cut sections, or make transitions, it will not do those.
If all you want is a conversion program that works like DVDFlick, I actually prefer AVStoDVD. It can use the HC mpeg2 encoder and produces superior results. AVStoDVD has no editing abilities however.
Both DVDFlick and AVStoDVD are free to download and use.
