I have now confirmed this crash-on-export issue is caused by
DV-NTSC decompressor with masked(clip/crgn atom) movie only.
Filed as new: radar 4560183.
This issue is still active under QT7.1. Sample movies are also included.

I have tried so long time with [theQTMovie

But QTMovie instance seems to be unstable on my PowerBook...
I believe this method with no attribute dictionary (passing nil
value), makes
simple reference movie, no modification to Movie object inside
QTMovie.
But If I tried to do stress test including this method,
"sometimes" it crashes...
"sometimes" it hang up... Following is sample test code.
I have found crash/hang at initWithFile, writeToFile, and release
of QTMovie.
I have also tried QTMovieOpenAsyncOKAttribute properties with NO,
but it does not help...
What's wrong?
(Xcode 2.2.1+MacOS X 10.4.6+QT7.0.4 running on PowerBookG4)
(I have also filed bug ID 4509486 weeks ago)
I ran this code ten times in a row and did not see any crashes at
all. Also on a PowerBook G4. Have you tried on any other machines?
Also, Radar 4509486 has indeed been received. No word on when it
will be addressed.
