Microsoft IIS Smooth Streaming help

Hi! I haven't find any already open thread on this, but I'm quite new to Serviio, so please excuse me If this topic has been discussed before. It seems I can't stream any video in Microsoft IIS Smooth Streaming format, Serviio won't recognize the url. It's something not implemented yet or maybe I've done something wrong?
I use Serviio on a Mac, OS X Mavericks, Core 2 Duo with 4GB Ram. Transcoding is enabled, but I'm using a set-top-box which is not included in the profile list. However, it works fine with every profile listed. I'd like to stream Microsoft IIS Smooth Streaming to my set-top-box, because using Silverlight on a browser window makes my Mac run really hot (95 C!).
I've found that every IIS streams is basically an HTTP address with an XML file (ie: http://www.sitename.com/directory/name.islm/manifest), which defines the video quality and the portions of the video to be played in a defined time. But I can't go any further, my knowledge stops here.
Thank you in advance for your help!
