I used both, did iTunes first then ultraV. I hear you might not can do it other way so iTunes first. though I'm on iphone I d/l the ultraV thru vudu player as was smaller d/l size. ITunes sd is 2.2gb and hd was 4.97gb. I'm not sure if I could of got hd version as I got code from DVD package but it seemed to be listed. The size was still to big on iTunes for my phone so I used the vudu ultraV the Hunger games website uses and d/l the vudu player on iphone and basic sd size was 700mb but still great quality.
