360 TV "Purchases" Anchored to Console

The ability to purchase TV shows to watch on your TV through your Xbox 360 has always struck me as superfluous at best. When I heard you couldn't play the shows on a portable player, like say Microsoft's own Zune, I was incredulous, to put it mildly.

But it gets worse. According to the official Usage Restrictions for TV downloads you can't do anything with them but keep em on your 360.
