OGMRip is an application and a set of libraries for ripping and
encoding DVD into AVI, OGM MP4 or Matroska files using a wide
variety of codecs. It relies on mplayer, mencoder, ogmtools,
mkvtoolnix, oggenc, lame and faac to perform its tasks.

The GUI features a clean HIG-compliant GNOME 2 interface and
tries to minimize as much as possible esoteric settings.
