@onimoD: you have to deal with resetting the source on tombstoning. http://developer.nokia.com/Community/Wiki/Resuming_streaming_audio_from_Dormant/Tombstone_state_in_Windows_Phone
we intentionally skip over a few things as they are far more advanced topics
@Victor: this was to get you started, 24 total videos
@alpha0721: nope, was seeing one thing that could cause it. Are you on Win8.1 Pro x64? Do you have the Visual Studio 2012 Update 4 installed?
@Beray Bentesen: where are you getting that from? I am not seeing any reference to that error.
