[Support #JDN-807839]: writeMovie produces an error when run in a script in the nightlies. [1178]

Greetings All,

I've tracked down the bug and am checking with Don (cc'd) regarding a bug fix 
put into the IDV between the 3.0 release (where it worked) and the 3.0u1 
release (where it stopped working). I just want to make sure I don't break 
anything with the addition of a single period in the code (I've ran some tests, 
but I'm a bit petrified about breaking bundles...just want another set of eyes)!

For a summary of the issue, as well as my fix and related issues, please see 
Bug #20 on Redmine:

> I am seeing this in the most recent IDV nightly (1/4/12), as well as in
> IDV 3.0u1 (11/29/11). However, everything appears to work fine in IDV
> 3.0 (8/29/11). In 3.0, the movie is created and you can open it without
