Quicktime Error -2045

Hi everyone,

I am trying to render a Motion 5 sequence in Final Cut Pro X (10.0.6).
When I send the render to Compressor (4.0.5), it appears to render successfully with the CPU maxing out at 100% for a few minutes and disk activity occuring as it would use source files for rendering. My problem with this occurs a few minutes into the render when my Share Monitor alerts me that "Quicktime Error -2045" has occured.

Has anyone else experienced this problem?
Thanks for your help.

Andrew.
