I generally buy movies/TV shows from Amazon Instant Video, but since they still haven't released an app for Windows Phone, I was thinking about buying a few favorites from Xbox Video. I know the Xbox Video app on Windows Phone doesn't currently support HD playback. If I buy a movie in HD, will it play on my Lumia 1520 in SD or will I get an error? If it does play, does the video fill the screen or do you get the black bars above and below the video. If I want a video to fill the screen, do I need to buy the SD version instead?

Also, in Phone Storage under Settings, I've selected for music and videos to be stored on the SD card. Does this mean if I download movies from Xbox Video onto my phone, they'll be stored on the SD card? Or is there a separate setting in the Xbox Video app?
