CitarRe: Combustion 2008 with Windows XP 64 Bit. Render to quicktime or .AVI settings?

I was use Windows x64 from about 2 years now. Just because y can assingn 100% of memory in catching option in Combustion. That´s gimme a pretty 3.71GB of cache, the max. for a 32bit program like C4. And the rest of applications still can use the memory C4 can´t see. My system have 6gb of ram.
But, yes, QuickTime in x64 is a pain! All versions from 7, gimme hard work to configure.
My best solution for the crash problem in Quicktime is:
Open Control Panel, click on "view x86 icons", click on the QT icon, this opens QuickTime Preferences.
In the "Advanced" tab, select "Safe mode (GDI only)".
That´s it. Maybe a problem with DirectX acceleration, maybe just for nVidia cards (like my case) or maybe just in my particular configuration. But works for me!
Good luck!
