How to stop iDVD from starting up?

After loading a DVD into my iMac, iDVD automatically starts up if I either cancel or quit the app the software automatically ejects the DVD. I'd like to know if there is away of preventing iDVD from automatically starting up ?

Do you mean DVD Player perhaps? Have you checked the app's preferences?

Unless things have changed dramatically (I am on an old version of OSX) you should be able to go into system prefs an under hardware should be a CD and DVD pane. In here you should be able to change how the system deals with DVDs.

As I said earlier, on an old version of OSX so YMMV.

Aye, yes your right DVD, but it was the DVD player preferences I neglected to alter that has done the trick thanks, Spheric Harlot.

And yes I run the old Snow Leopard, call me old fashioned if you like, but if I bought a new mac again I would insist on nothing less than it.

If you bought a new Mac again you would insist on Snow Leopard?

So you're never buying another Mac, ever again?

Snow Leopard indeed does not run on any current or future Macs, but Mountain Lion is pretty nice and his fixed most of the Lion silliness.

Indeed. Mountain Lion is actually quite a bit awesomer than Snow Leopard was.

The only potential annoyance here being the death of Rosetta. But that hasn't really bitten me yet.
