Weird crashes outputting QT and/or rendering

Question

I keep getting unexplainable crashes when either outputting a QT (from timeline or viewer) and/or when rendering on timeline. Using FCP 6.0.4, QT 7.5. It's happening pretty consistently. Tries trashing prefs- no change. Generally, all system parameters are properly configured (Disk Warrior all drives, all caches clean, etc.
The Crash Log for the crashed thread (on every crash) looks like this:
Thread 39 Crashed:
0 ...pple.AppleIntermediateCodec 0x0c265505 iCodecDecompressorComponentDispatch + 31675

3 libSystem.B.dylib 0x915d86f5 pthreadstart + 321
4 libSystem.B.dylib 0x915d85b2 thread_start + 34
As you can see, I'm working AIC.
Any help much appreciated. This is a new problem.

Thanks Jerry. Yeah, my system is likely not the cause.
As far as media goes... I capture native and then transcode to AIC via Media Manager. The problems I'm having are not clip-specific as far as I can tell, so I doubt media corruption. I make feature documentaries, so there's a LOT of media being used (100 hrs +). I just finished a long (3-year) project utilizing the exact same workflow, with no problems (although it was on my old PPC, which is why I am wondering about the Intel possibilities).
I'm wondering about the efficacy of re-installing QT, or FCP, or if there is a way to replace the FPC codecs for AIC only? Is this related to the preset files you find within the system (in the "Custom Settings" folder)?
