I have the same episode, but between all of the commercial breaks there is a total of at least 80 seconds of black screen, which would bring the actual running time to less than 48 minutes.
Hopefully all five seasons get released, and it doesn't get abandoned like "Mr. Novak" seems to have been, or "The Eleventh Hour". Any word on the second seasons of those shows getting out soon?
The first season release, available as of October 9, is split into two volumes with 16 episodes each. $34.99 on Amazon, but might be cheaper at other retailers.
