I have an Xbox and Windows8 and have been waiting anxiously for the "Play To" feature to work in xbox music and hopefully other things. Now that we have the new Xbox dashboard and the windows RTM has been updated, there is still no play to feature.

Am I missing something or do I have to do something special to enable it??

Smartglass is working ok with my xbox.
I have enabled play to on my xbox.

Xbox music on windows 8 still has no play to feature. Why?
