“I’d been wondering about this,” Kirk McElhearn writes for Kirkville. “My bandwidth is somewhat limited: I have a 50 GB per month limit on my satellite internet, and my DSL is only 2 Mbps.”
“So I had switched iTunes to download 720p movies instead of 1080p. (You can do this in iTunes > Preferences > Store),” McElhearn writes. “But I saw today that the iTunes Store has the extended versions of The Lord of the Rings trilogy in HD for only $30. I don’t have them on disc; I used to have the Blu-Rays, but gave them to my son. I wanted to buy them, and was curious to see how much difference there is between the two different qualities.”
McElhearn writes, “A difference of 1.4 GB; or about 5% more to get the 1080p versions instead of the 720p versions. And that affects not only your download size, but also the amount of storage you need.”
