You'll be able to watch all available CSTV duals (they offer the service for a lot of schools) if you buy the $14.95 one.
The $9.95 one just gives you OK State duals.
Jensen, I want to watch the OSU vs Gopher wrestling tonight. Do you know what the difference is between the cstv XXL and Oklahoma State package for the live streaming? The cstv XXL is $14 and Oklahoma is $9, so I'd guess you get more for the XXL one.
