Consider this scenario:
I ask for a Bethesda game for my birthday. Two people buy me the game. I don't know where they purchased the games.
How do I sell the one that I don't open? Ebay? Amazon?
Is the game that I sell covered by a warranty? It better be!

When I first read this I thought "what aren't so big??"... my imagination ran...

One great reaons for time shifting radio is Sports. If your team's radio announcer is better/more enthusiastic than the network dullards, time shift their radio broadcast by 3-7 seconds to compensate for the delay of video bouncing off satellites!
