It’s possible. Some programs work the processor harder than others. But it’s also possible the project file is corrupted somehow, or maybe it’s trying to use more memory than you have.
I’d try restarting and making sure no other programs are running before starting DVD Studio. Maybe even turn off Bluetooth and the AirPort. If it still quits, I’d run Console (in the Utilities folder) and see what error messages it throws when DVD Studio quits. Even if the messages don’t mean anything to you, they might make good Google fodder.
I have been reading around on Mac forums about issues similar to mine. It seems that DVDSP is a really sensitive program, installing the wrong thing could cause it to crash. However i didnt install any new programs. I put new sound effects in Soundtrack…i can’t imagine that would do anything to DVDSP though…
