I do have Versus and cannot find Ultimate Diver Challange.
Into the Drink is on at 9:30 AM Saturdays on HD Net, then repeated at Noon. There are only sporatic repeats now, they are gearing up for the new season (2). Tons of bad reviews got the original host, Aaron Fauls, launched. If they do not change the show significantly you will be very disappointed. Seems the "Drink" they focused on was alcohol, bars, distilleries, and if we were very lucky we got 5 to 10 minutes underwater. If ever there was a show needing a DVR this was it. Got my fingers crossed.
