This issue can occur because of audio or video driver issues on your PC. The following scenarios may apply:
- Your current video driver may not fully support Windows 8 or Windows RT, or the playing of DRM protected content.
- You need to install the update KB2768703 to resolve protected content playback errors in Windows.

At this time many USB video cards do not meet this requirement. Please contact your video card manufacturer and search for and install the latest Microsoft WHQL-certified video driver for your hardware.
