VLC Media Player is one of the most popular multimedia players for various audio and video formats (MPEG-1, MPEG-2, MPEG-4, DivX, mp3, ogg, etc.) as well as DVDs, VCDs, and various streaming protocols.
The program is free to download and install on any Macintosh computer running Mac OS X Leopard. The people behind the VideoLAN Project have released a stable and much improved version of their VLC Media Player for Mac OS X, adding a number of new features, codecs and the usual laundry of bug fixes that any piece of software needs every now and then.
