How can I get a gworld (or port ... or windowref) from a NSWindow (nib) or NSView pointer ?

Unless you're using an NSQuickDrawView, or initialized your NSWindow with a Carbon WindowRef, I don't believe that there is a way.
What are you trying to do? If you want to use some of your already existing code that uses CopyBits, etc, but display it in an AppKit window; then your best bet is to use an NSQuickDrawView.

Currntly my program crashes when i try to capture something to disk, I looked at the HackTV code and did it the same way, but the SGIdle function just returns error -34 (but my disk isn't full ...) and when SGStop is called the app crashes with signal 10 ....
Any ideas ?

I'm not sure how you do it from an NSView though. Probably some combination of getting the NSGraphicsContext from the NSView, NSGraphicsContext is a peer to Carbon's CoreGraphic's CGContextRef so you can probably do some massaging to get at the GWorld pointer from there.
