Which of them: the crude orange one (MPEGPlayerMorph)
or the nicer blue one (MPEGMoviePlayerMorph)?

The X handle (halo) that deletes the morph ?

Whats in the debugger ? My first guess is that this is a bug that 
occur on *nix because the MPEGfile path is invalid. 
I did some hacking to force stuff to work: The MPEGPlugin chocked 
on filenames with uppercase suffixes. So I forced lowercase because
HFS ignores cases. And I probably did some other hacks too...

I do not see any of this on my Mac system.

The plugin is great! It also plays MP3s so a soundcard is recomended.
