SmallDVD is a simple DVD authoring utility for MacOSX that will take video files and create a DVD image from them that can be burnt using Disk Utility.

It is an AppleScript front-end for dvdauthor and a variety of other existing command line tools.

I use MPEGStreamClip to edit the MPEG2 files recorded from TV, create the disk image in SmallDVD, then burn it with Disk Utility.

I wrote SmallDVD because I couldn't find anything else that let me create a DVD with several files, and a simple menu with a static background image. You can read about my failed search for a similar app here.
