LinDVD
LinDVD from Corel was a commercial proprietary software for Linux for the playback of DVDs and other multimedia files. The latest version supported ultra-mobile PCs (UMPCs) and mobile internet devices (MIDs), as well as a streaming media and a wider range of standard and high-definition video and audio encoding standards.
LinDVD can play copy protected ( CSS) DVDs. Certain distributions like Mandriva have included this software in their commercial Linux distributions, and Dell is now preinstalling it on their Ubuntu systems.
Corel removed all information about LinDVD from their webpage, that is, LinDVD is not supported anymore.
