not that it stops me from d/l 4K whenever available (and provided it's a starlet whose scene(s) I want to keep in my collection), but all 4K videos are shown as "4GB."
well, most of the 1080p ones are 4GB -- or some variation thereof, but the 4K UHD scenes are usually over 12GB in size. It might be a good idea to indicate that on the d/l page.
