pix_film/movie are designed to handle video only, so sound does behave
oddly using pix_film/movie.  It's really only in there by accident and
because I made a special build for my friend to use at one point.  I
obviously never checked in that build because it had volume control as
I recall.

Auto mode on OSX hands off all of the movie tasking to Quicktime
because it resulted in much better playback with multiple movies at
once.  It's not good that the behavior between platforms is different,
but then again we've tried to make the Quicktime related objects work
as well as possible and not work against us.

We use the XCode project to maintain and build GEM on OSX.  It's free
and comes with the OS in most cases, but you have to learn it and also
sort out the libs like FTGL.
