Holy cow, that's all? Talk about over compression! I always like to compare 1080p24 of Fantastic Four: Rise of the Silver Surfer. Movie is only ~90 minutes and required a BD50 (that's a 50GB disk) to record compared to the first movie, which was long and published on a BD25 disk. I cannot imagine how blind I would have to be to accept 6GB for a 2 hour 1080P movie. Well, unless it is 2 hours of 1080P of a black screen.
Yeah, they use pretty heavy compression. I mean, it can still be 'good' quality, most good quality torrents you find @1080P are around the same size. Bear in mind that the blu-ray disks tend to come with a handful of different audio tracks, special features, commentary garbage, behind the scenes stuff, etc. That can eat up a bunch of extra space pretty quickly. I'd say 12GB is about the most you'd need in a raw format to actually get proper 1080P with a single audio track, but Netflix does have bandwidth to consider so 1/2 compression seems okay.
Sharing windows folders and copying particular \steamapps might be a solution.
That can work, but bear in mind steam tends to have a mind of its own when it comes to what data it accepts. If you move the data over and tell steam to 'install' over the top of the directory (to activate it proper), sometimes it'll redownload anywhere from 0-100% of the files, based on whatever reasoning it comes up with. I've done this more than a few times with varying results.
In your example that's 120 movies a month, and 240 hours of watching. Dunno, seems like that's stretching pretty far, and in your example you could fit another 40 movies in and still be under the cap.
Yeah, it was an obtuse example but not completely off-base, especially for 5 people. Do you not know people who just put on movies/tv shows in the background while doing whatever? I know I always did growing up with homework, or while playing games or whatever. Not hard to have a second screen with whatever Netflix playlist on autoplay (that's what the GF and I do, much of our crap is downloaded though and we don't have a cap, thankfully).
