I spent a little time trying to find a DVD player for Gutsy Gibson that will support DVD menus and play a ripped DVD from a folder. I tried Totem and gxine before I came across VLC media player.
VLC media player is a highly portable multimedia player for various audio and video formats (MPEG-1, MPEG-2, MPEG-4, DivX, mp3, ogg, …) as well as DVDs, VCDs, and various streaming protocols.
Make sure the “universe” repository is activated before using the Synaptic Package Manager or Add/Remove software.
Once installed it’s just a matter of selecting File->Open Directory or Ctrl-E.
