“Play To” is a feature of Windows 7 and 8 that will push content from a local computer to a compatible rendering device. In my case, I push video files from my local computer to my Xbox 360 in just a few clicks. It works great… when it’s working.
Thankfully when the “Play To” fails to open the application on the computer to push to a device, there’s an easy fix.
Simply open Task Manager and look for “Windows Digital Media Controller Application” in processes and kill it.
Then go back to the “Play To” menu and try again and it will work.
