Rick Reitmaier is an engineer on the Flash Player team (formerly of the Flex team) and gave a talk at Stanford a few months ago about the virtual machine used by Flash Player 9 (AVM2). This is the stuff that we've contributed to the Tamarin project. The first 20 minutes or so are getting the folks in the room up to speed on Adobe/Flex, etc, but he begins getting deeper after that.

Very cool. FYI, it looks like the link is Windows-only. At least it doesn't work on my Intel Mac.
Link worked for me on Intel Mac (MacBookPro), but I had to use Windows Media Player to open it.
I'm not getting any sound on two different windows machines using Windows Media Player 11... any suggestions?
Thanks

I will be very happy to know any web to learn details about flash player
