@hawkeye10,
Another thing about having a DVD at home is that you can switch on its subtitles so you don't miss a word that might be mumbled, and you can also pause it anytime for a tea break, or rewind/fast forward/ slomo it etc, wow what tremendous power..

Oh and you can also take screenshots off the screen with your digicam to post in discussion forums like I did with these 'Gravity' shots-
Poor Sandy Bullock is left drifting helplessly in space after high-velocity orbiting debris shoots the Shuttle out from under her..
..and wonders how the heck she's going to get back to dear old Mother Earth.
Hmm tricky one...
