Well, that makes me more confused than ever.

It is definitely not blocking. It is showing full motion mpeg video
and sound from a ripped vob file of a DVD of the matrix. Lots of
motion, quick cuts, etc. And all this while not showing up on top at
all.
Here's another possibility. I'm runnin 2.3.99.pre3. Could that be
confusing top? The GIMP shows up on top fine.
I could run a time consuming filter in the GIMP with with no
noticeable slowdown while my application is running with no noticeable
affect.
Something is weird, here.
