Any other solutions regarding the sudden Quartz extreme message for iMovie?

iMovie suddenly won't open (Quartz extreme required) and no solutions mentioned here seem to help. I've tried changing the resolutions temporarily, restarting, permissions repair, deleting the com.apple/imovie.plist from library preferences, software update, deleting iMovie then redownloading (from an external HD), and it's still not opening even though I've made movies in the past. I did download the iDisplay app to use an ipad as a second monitor, which I thought may have caused the problem. So, I deleted iDisplay from my HD and emptied the trash. Still no iMovie. I'm outside of warranty and don't want to pay money to have Apple Canada fix their own issues - so please help. Thanks. 

I have the same problem on my brand new MacBook running 10.5.4... One suggestion was to change the colors from millions and then back but I don't even have that option in my display panels. In another thread I found something that worksL
If I simply log off and back on, then everything is fine again (no need to restart). It will show it as supported in the system info. At first I used to restart, but for the sake of trying it out once, I decided to just log off and on. It had the same effect as restarting, so that's what I do now.
ANd in yet another answer I found something that worked for me: change the display resolution and then change it back.
Obviously some display setting is getting corrupted in some fashion and in my case I'm using with and without an external monitor, so perhaps it loses some needed preference...
