Thanks to a quicktime export tutorial
[http://freevlog.org/index.php/2006/04/26/443/], I'm now able to export iPod
compatible videos using the dual-pass divx codec.  The problem is, it's a
time-consuming task so I thought I'd try to automate it with applescript. I
took a look at the QuickTime applescript dictionary and concluded that UI
scripting will be required.

Below is the script I started.  The problem I'm running into is a drop-down
menu that I can't seem to select.  I try selecting it with arrow keys, but
doing so doesn't update the menu below it.  It's not obvious it hasn't
updated until you click the Options button after running the script.  It
shows the options from the initial selection. Very strange.

Anyone have any ideas?

Many thanks in advance,
Simon
