Although I have only recently found swftools, I have worked with MM
produced SWFs for over 5 years, so if you will indulge me I will tell you
what I have learnt.

To use FlashVars in a MM produced file, you do not declare the variable in
the movie at all, you just use it.  You will find that if you do try to
declare a FlashVar with a var statement in actionscript it can wipe out
the value passed in.

We also found the the passing of FlashVars can be unreliable (in some, but
not all versions of a browser) unless you also pass the value in the movie
part of the embed & object tags, eg:

<PARAM NAME=movie VALUE= "movie.swf?text=hello">
<PARAM NAME=FlashVars VALUE="text=hello">
and
<EMBED src="movie.swf?text=hello" FlashVars="text=hello">

Make sure that all variables you are passing in are in all places.  Any
difference between FlashVars and param & embed can cause problems that are
difficult to debug.

Check out this KB for a bit more info.

We never used the MM provided javascript to insert the movie into the html
due to the issues we had when FlashVars didn't match the param & embed, it
was quicker to write our own that just took care of inserting the
variables in all places.
