DVDforger is a DVD authoring application which creates DVDs from almost any kind of video files (if the necessary codecs are installed). it supports multiple titles with multiple audio tracks, subtitles and a simple menu. It is basically a GUI for a set of free tools including AviSynth, HC Encoder, Aften and dvdauthor.

No installation is now required - just unpack the .zip file and run DVDforger.exe. However, you have to have AviSynth, a video frameserver, installed on your computer. If you don't, DVDforger will automatically install AviSynth when it's first started (it asks for permission first).
