When I run "mps" from the command line, I get the error message below. My Mac Pro reports 24 processors (12 cores + hyperthreading), which appears to be more than what mplayer will allow. Would you have MPlayerShell check the number of processors and make sure it is set to at most 16 threads?
The threads option must be <= 16: 24
Error parsing option on the command line: -lavdopts
