Help with an FCP 5.1 crash

I've truncated the message where the ellipses stop occuring in the report. I have swapped ram, cables, hard drives, video cards, fiber cards, and everything I can think of in an attempt to isolate and correct this problem, with no luck whatsoever.

Any help would be met kudos, admiration, and more than likely fawning.

Thanks!
