As I said, you have to get the extra cost stations with COX in order to get the Brigham Young University (BYU) station. As I recall, you have to look for it among Cox' Digital TV offerings in teh 200 or so channel number series. (BYU-TV is the Morman Church TV outlet so you might have to sort through hours and hours of "stuff" to find what you're looking for.)
I used to use COX until I realized how just bad and flaky their technical services are. When combined with incredibly snotty customer service and ridiculous charges for repair services, a digital telephone "service" that might work one day but not the next became a bit more than I needed to put up with.
I switched to Cable America and haven't had a moment of regret since. (And it's less costly to boot!)
