I want to buy season 2 of the TV series Young Justice so I checked the WP Xbox Video app for the price. Looks good. About $25. So later I go to the Xbox Video app on Windows 8.1 and, what the heck, it costs $45. Don't your video purchases sync across operating systems and devices? Why is there this enormous price difference? If I bought it cheap on WP would I not be able to download it onto my Surface? Can anyone shed some light?
