Thoggen is a DVD ripper for Linux within the GNOME project.
Thoggen can back up DVDs by re-encoding them using the Ogg Theora video codec.
It attempts to hide the complexity many other transcoding tools expose and tries to offer sensible defaults that work well for most people most of the time.
The Theora implementation used is far from optimized, and at full DVD resolution, encoding can slow down to the single-digit frames-per-second count, meaning several hours are required.
