I am trying to pass query string value to an actionscript .swf file that is locally stored on a DMP 4400. According to Chapter 5 of the Cisco Digital Media Designer 5.2.X User's Guide I can use the fl_flashvars= value for the 4310. What is the similar construct to do this on the 4400 and the 4305?
 
I want to be able to load the .swf file with a command similar to the one below, but with extra arguments that tells MyViewer.swf where to go get the rest of its data.

Also, I am extremely new to action script. Any code snippets that describe how to pull the query string values from within an actionscript would be appreciated.
