I have been testing streaming to WDTV from the Metro interface as the WDTV is now certified.
As stated in my last post the Xbox Music App will not let you stream music that you do not own. No fault of the WDTV live streamer as you can stream your own music held in storage from this app.
To do this right click on very bottom of the screen and Open File will appear. This allows you to view and stream your own music library.
As you can already do this via Windows Media Centre with the play to opion at top right of screen and the user expericence is better then why bother to use the new xbox music app.
Also you can use serviio or network share to access your music collection via network.
Here are a couple of Win 8 apps that I have found do stream to WDTV…
Fildo… allows search for music + play list.
Sounddrivin… lots of music if you like exploring.
I have not been able to get the win 8 App Catchuptv to stream.
I can’t get Yesterday TV via sat so that would have been nice.
I just get a message “media from catchuptv” and a blank TV screen.
I do have an ethernet connection and stream movies from my Nas - guess the WDTV can’t handle the streaming format of catchuptv ???
Hope above has been of some help.
