Media Playback component & variables...

[RobbieC]

I'm trying to get a Media Playback component to play videos. I can get it all to work if I hard code the component with this code:

video/1234.flv

but I'm trying to get it to work by parsing a variable into it using:

video/+variable+.flv

the variable is parsed into the movie using:

main.swf?variableID=1234

and the code within the movie to identify the variable:

var variable = _root.variableID;

but it doesn't work, although I can't see anything wrong with what I've done.

Is it actually possible to use Media Playback component with variables?

Thanks in advance for your help.
