UMPlayer is the multimedia player that fills all your needs. With
dozens of advanced features and built-in codecs it can handle any
media format, and can play Audio CDs, DVDs, (S)VCDs, TV / Radio
cards, YouTubeâ„¢ and SHOUTcastâ„¢ streams and even incomplete or damaged
media files.

This SlackBuild builds from SVN.

I have provided some black background images which can be applied by:
