you should be able to download it ~10 minutes after it airs (after its over)...
that is the usual that I have seen...
even for 40 minute/1hr shows.
I am on the west coast... If a show airs at 10 PM (all time zones, staggered), I can download it by 8:05 PM PST (which means that it was edited for commercials, encoded, and uploaded within 10 minutes after the credits roll)
