Just a quick post to let you know that one of my friends on the forums discovered that if you are using the VS 2012 simulator and playing back video, if you change the orientation of the simulator, the video will stop playing back. Actually if you handle the "media failed" event you get an error. The error is a bit strange and complains about audio. This is actually a known issue in the simulator.Unfortunately I don't when or if this is going to be fixed. The team is aware of the problem though so I expect that we will see a fix sometime in the future I just can't say when. The good news is that this problem doesn't affect a slate / tablet / surface device. The issue is specific to the way the simulator is creating a remote desktop connection back to the host PC and remoting audio and video services.
