Well, for that matter, is shooting a TV screen with a camera "really" what you'll see?
The point is not to show WHAT you'll see, but rather to just compare the differences. It shows that AppleTV rentals are "close" to Blu-Ray and "better" than DVD.
That's what the point is here, and using JPEGs doesn't negate that lesson.
Hm. True. I guess I jumped the gun on that one...
