And final video performance is very dependent on the design of the individual flash code it's accessed from!

Don't expect everything to work with 3% cpu like vdpau in myth, this is a partial solution that is really easy to screw up in your flash code.

I did some projects with hw accelerated flash video a little while ago, it's a big help but it's not a magical complete solution.
