FYI to all who may be interested:
A torrent of this Game 5 finally got posted on the Davka BT site (aka the best site for downloading full NBA games). Unfortunately, since the broadcast didnt start until 9:32 left in the second, that's where the torrent starts, but it's better than nothing.
It's available at:
http://bt.davka.info/. Scroll down a bit and you'll see it.
