According to comments on the HandBrake site, this...

MediaFork 0.8.0b1

...release is authorized fork of HandBrake and that the two projects intend to join forces sometime in the future. Like HandBrake, MediaFork is an Open Source DVD to MPEG-4 converter. The site says it is available for Mac OS X, Linux, and Windows. However, as far as I can tell only the Mac OS X version is currently available for download.
