I also search around for this a lot and could not find any useful information.
But maybe an alternative for you would be to place the adds on an invisible DIV layer above the flash? Than make flash communicate with javascript to trigger on and off the ads in the proper time.
For the user it would seem like the ads are part of the flash.
Best of luck,

as far as i know that would not be possible, due to the fact flash cannot display "webpages" inside itself, meaning google ads would not be able to be placed within the swf file ether, I asked about somthing similar to this, and that was the answer i got a long time ago.
