Look into

 Yes, MPlayer CVS-020221-00:00-3.0.2
In fact, I was doing some testing with the 0.60 version and it works better
than the latest CVS. (0.60 will at least do the quit function) Is there a
compiler/config option that I should be using ??? It seems that I must be
doing something wrong.

Thanks again

Tom

P.S. If you can give me a brief overview as to how it is 'supposed to' work,
from a code point of view, maybe I can do some debugging at this end.
