Infuse Pro: what additional features do you get?

I’ve been reading the Infuse webpage and from it I can’t tell what additional features are added when you upgrade to the pro version. Besides Dolby surround support, what else do you get with the Pro version that you don’t get in the free version?

You’re mainly paying for the licenses for dolby digital and Dolby DTS etc… It’s $10, but that’s a one time fee which covers all your apple products. Currently, i’m using it on 2 apple tv’s and my ipad air. That’s cheap, i would just pay it and never have to worry about some movies not playing due to audio licenses.
