There was just a release of Xbox Video for the web, and Microsoft has decided to follow up with that by releasing an Xbox Video app for Windows Phone 8. Users will now be able to rent and download content via their mobile device. The Xbox Video app also has the capability of letting users view content they have already purchased, as well as downloading content straight to their phone. You can only view content on the Windows Phone 8 app in standard definition for now. You can also access Xbox Video through Windows 8, Xbox 360, and Xbox One.
