Hi,

I tryed all you told me.

But Catalyst still crash when I want to use the Blackmagic Video- Input.

I downdate my OS to Mac OSX 10.6.0. but still have the same mistake.
If I open a new show the videoinput will work for about 5 seconds (I can see the inputvideo), after that time Catalyst crash.
If I open the Catalyst with the showfile, it will crash after startup.

I also tryed every possible driver version for the Blackmagic Intensity Pro,
but everytime the same.

The "Bride of Mung Grab" you told me to use also crash.

On my MacBook Pro with 10.6.2, the iSight Camera work in Catalyst, and also the "Bride of Mung Grab" will show the videoinput. No crash!

Maybe you can give me some more suggestions what to do.

Thanks for your help.
