More on the Audio Only Canvas requirement....

Actually the possible bug I described in my earlier post is more serious
that I had originally thought.
I was willing to accept the fact that you had to have an on screen QTCanvas
in order to play audio only files. However, my application is a lightweight
app and hence I use a JQTCanvas instead. However, QT throws a bunch of
errors when setting the JQTCanvas objects client to a MoviePlayer that has
nothing but Audio (See stack trace). This is the same "PlayMovie" example
but with the QTCanvas object changed to a JQTCanvas (and the frame to a
JFrame of course).

So now whats my solution. I need a canvas to play the audio, but can't
create a canvas for audio only???

Any thoughts any one?
