Huh? First you said that uncompressed movies take up about 25gb for 2 hours. Blu-ray movies are generally around 25gb, which leaves the second layer free for extras or whatever.

Then you said that "blue-ray is not uncompressed video (thus, 25GB holds a 2 hour compressed movie)" By your own math they would only take up 12.5ish gb if compressed.

I actually am curious what digital cable uses. It's definitely 720p in my area, and probably compressed, but not highly.

Actually, Matt, you claimed uncompressed movies take 25GB for two hours. Right up here: http://news.ycombinator.com/item?id=99416

What I said is, Blu-ray movies take up on average 25GB with MPEG2 compression. In other words, your original estimate of the size of things was wrong, as was your implication that blu-ray was uncompressed.
