Abstract
The media player employs an operating system that supports a virtual machine into which auto-run playback programs may be loaded and run. The auto run playback program is stored on the media containing the program content, such as on an optical disc medium. When the medium is inserted in the player, the auto run playback program automatically launches and is thereafter used to access playback the media content. Support for legacy media is provided to allow the player to playback compact discs and DVD discs that were manufactured without the auto run playback program
