A new Xbox 360 update has been or will shortly be released, as detailed by Microsoft's Major Nelson. It's the usual mandatory download, dropped on you when you sign into Xbox Live, and is designed to address problems with those newfangled Xbox Video, Xbox Music and Xbox Smartglass features.
"I wanted to let you know that the team has just released a system update for the Xbox 360 over Xbox LIVE," writes the Major. "Starting today when you sign in to Xbox LIVE you'll receive a prompt to accept this mandatory update. If you are signed into LIVE already, you may be signed out and asked to accept the update and you'll be back online in a few moments.
"In this update, we are 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 that some were experiencing. Thanks and we will see you online."
How are you all getting on with SmartGlass, incidentally? I'd have written more about it, but my smartphone's done broke itself in mysterious Ribena-flavoured circumstances.
