MPLAY Multimedia Player is a multimedia player for the Macintosh that supports a wide range of media formats. Originally designed as an MP3-Player, MPLAY has grown to support many audio formats, as well as images and video. 

MPLAY has all the features you would expect from a multimedia player: playlists, skins, easy operation and lots of special features. Among the special features is the audio track mixer. This function permits the mixing of two tracks (enabling DJ-like mixes) made possible with MPLAY's two separate playback engines.

I recommend you to read this Reference to learn all about the features and possibilities of MPLAY!

MPLAY will play all audioformats, videoformats and  imageformats supported by the QuickTime version installed. Therefore, you should always make sure you are using the latest version of QuickTime (http://www.apple.com/quicktime).
