Dave,

I haven't tried what you are doing before so I'm not sure why you are  
seeing the behavior you are but if you can't get it to work you could  
try the EnhancedQT external which can export frames in PNG format to  
a variable. I'm not sure if this is documented in the version I have  
online (qtSaveMovieSnapShotToFile
  is though) but it is there and uses the API so it should be  
reliable. I could also just pass you along the handler from the EQT  
external if you wanted to incorporate it into the external you  
already have for this project (seems like you've been working on once  
based on your posts here).

  * @param  MaxImageHeight
  * @param  MaintainAspectRatio (default true)
  * @param  Time (empty or < 0 to use movie poster frame).
  *
  * @return empty or error
