I have a G5 Dual 2.7 with a Radeon x800xt agp card for my main display and a Radeon 9200 pci card for a second display. With the 9200 installed iMovie gives me a message that, "one or more of your graphics cards does not support Quartz Extreme" and then it gives me no option but to quit. iMovie HD launches with about the same message but allows me to continue saying that certain abilities may be disabled. As far as I know there are no pci cards that support QE. There is nothing in the iMovie specifications indicating that I should be having this experience. The only requirement listed is a Quartz Extreme compatible agp card, which I have. There's nothing about additional cards disabling any of ilife 08s features. I should mention that I also have a video capture card that disables the app. as well. It seems a poor application anyway when I pull the 9200 out, but I did pay for it so I'm getting angry. My question is: Does anyone else have a pci card installed and has been able to get iMovie (now 7.1.4) to work? And as I've been dealt by Apple rather contemptuously on this, does anyone think I have the basis for a law suit? And, just in passing, because someone has their signature set to say the opposite, if Snow Leopard doesn't run on my G5 I'm through with Apple products forever.
