What "format war"?  Everyone already standardized on h264 years ago, and there is a built in h264 decoder on damn near everything these days.<p>Keeping two copies of every movie would be a waste of CPU cycles, disk space and bandwidth (Theora videos are bigger than their h264 equivalents).  Dropping support for h264 in favor of Ogg is also not an option due to h264 being in everything.
