The stream changes its episodes at 5 PM Eastern. I was watching Body Language on Wednesday around that time. Only the first 5 minutes aired, then the stream went to the next chronological Beat the Clock.
Also, it appears that their stream repeats every week; last night, I saw a Beat the Clock which was on the stream late last week (I wanna say the 4th ep., the second show with the big penny bonus stunt), Body Language with Marcia Wallace and Fred Travalena, and a Card Sharks from the premiere week, either episode 3 or 4.
