There’s no shortage of quality free media players to entertain your eyes and ears, regardless of your computer or operating system. With cracking cost-free solutions like VLC (often considered the king of media players) and iTunes alternative JetAudio, you really shouldn’t be paying for this sort of software.
Universal Media Player, or UMPlayer for short, is yet another addition to the media player category which uses the MPlayer backend to chew through any media you give it. The app promises to play everything and integrates various web services into one desktop solution.
There are versions available for Windows (XP, Vista and 7) and Linux (Ubuntu and Debian binaries and an RPM) with a Mac OS X version currently in development and destined for release any day now. The version I’m testing here is 0.9 (Linux) on Ubuntu 10.10.
