I remember when ATV3 was announced Apple said any previously purchased movies will be upgraded to HD with the HDTV. I have over 40 movies I got with Digital copies. I have them all on the cloud but when I download them off the cloud or stream them they are in SD. I have about 5 that are newer that are HD. Does ATV3 stream them in HD? Or is this not working for me because I technically didn't purchase them from Apple?
