I'm not sure I "get" Blu-ray.
Rather than go dig, you seem to be on top of it, so,
What does Joe Consumer do with it?
The item says B-r commercial movies (the list) will play in existing players, but in HD?
For Joe to get into this, does it mean a new HD camcorder, a new B-r recorder/player, and HDTV to see it?
Is this a new money-pit? (a worthwhile money pit?)
