Quicktime with Rev

[Mark Swindell]

I drag the QT player icon onto my card, and then set the source to an 
.mp3 file (which plays back fine on the system's QT Player) and the 
player blanks out and goes away save for the bounding rectangle.  I set 
the source to an mpeg source and it works as it should.  This is with 
2.5.1, Panther 10.3.8.   What don't I know that I should?

Thanks
Mark
