Thanks to mighty Google, now you can get FeedBurner Stats Pro and MyBrand version free of cost.
MyBrand is a premium FeedBurner service that allows publishers to showcase their feeds by serving them from their own domain. For example I can now use rss.theos.in instead of http://feeds.feedburner.com/ComputerTechnologyAndOsBlog
You need to setup a CNAME which is nothing but an alias or shortcut from one Internet name to another.
To get MyBrand:
a] Sign in to your FeedBurner account
b] Click My Account
c] Click MyBrand, enter your domains and activate
d] Just send email request to them
Thank you for making service free for all of us :)
