It can't find MPlayer, UMS uses a part of MPlayer (MEncoder) as a transcoding engine. I don't know the install procedure for Linux, but MPlayer needs to be installed somehow.

Sure it cant find mplayer, but please ... in case of not finding a simple file UMS may log a warning but never throw an unhandled IOException or spam the log with the stack trace! This is really no good coding stil.

Not that I think it's that much of a big deal, but I changed it so the next version won't throw a stack trace. The Exception wasn't unhandled, it was just logged with full stack trace.
