Thanks again guys.

Hmm... I have FireFox 3.6.3 and it doesn't do that. Then again, I am in North America so that might have some affect. Why it would be chopping off the file part way is beyond me. I set the script to not time out as it generated the file. I am working on rendering a smaller file size (with reduced resolution of course) so that if these sorts of issues come up yo can at least get the thing.

What are your email addresses? I'll email you the issue directly.
