Windows DVD Maker is software bundled with Windows 7 Home Premium and Ultimate. There is a tutorial here
. It doesn't work with Bluray, though.
If you are creating the master video files using an authoring program, any CD/DVD burning software can burn it to disc, including Win7's burning app. because the correct formatting, menus, etc. have already been created by the authoring program (DVDlab, DVDA, Nero, Win DVD Maker, DVD Santa, etc.). BTW, the Audio_TS folder is usually empty for a video DVD, but the folder must be present for the DVD player to recognize the disc as a DVD.
