I purchased a movie thru microsoft store(gift card), I downloaded it to usb flash drive, but I am not very techy, so I did my best trying to burn a dvd-r. It went thru the motions, I think, on the screen but I never felt the optical drive moving. I have a Samsung blu ray player with a usb port. This is why I wanted a copy. Anyway, player just stays at loading and never stops. When I check the usb it's on there, but says I need to sign in to my MS account before it will play. But it plays fine on my computer. Can somebody please help me? I don't know where else to go from here.
