What can be Miracast on WDTV other than Youtube, Spotify and local casting files

I have been playing with Miracasting youtube and have used the Android app LiveCast app to play MKV Files (from my Serviio media server) and mp3 files. 

Are there any other audio services (online radio services) or video services (HBO Go, Showtime Anytime) that can be Miracasted.  

I don’t do Spotify but I see that it is enabled.  


I tested a few. The best news is that Netflix and Popcorn time can be mirrorcasted, inclusive sound. And Spotify can be streamed directly to your amplifier withhout your television on.
