Microsoft has just released a mandatory system update for the Xbox 360 over Xbox LIVE. Starting today when users sign in to Xbox LIVE will receive a prompt to accept this mandatory update. Those signed into LIVE already may be signed out and asked to accept the update and they’ll be back online in a few moments.

In this update, Microsoft's team is correcting some issues such as displaying the incorrect playlist name when launching a playlist from Xbox SmartGlass to the console, an error with Xbox Video closed-captioning and an error with Xbox Music.
