brycy,
I live in Chicago. It's kind of confusing. We no longer have Fox Sports Net in Chicago, so Comcast Sports Chicago has agreed to carry the "standard" Fox Sports Net Saturday college football games on their channel when there isn't a local Chicagoland team on Comcast at the same time (Blackhawks, Bulls, Northern Illinois, etc). Tomorrow, the Northern Illinois game starts at 1pm, so it is being aired on our standard Comcast Sports station. So, they are putting the Big 12 game (
ISU-OU) on another channel (channels 3 and 100 locally). I assume that's why it is showing on your Chicago Comcast Alternate station. In your situation, its probably best to have Chicago Comcast / Chicago Comcast Alternate because you'll always get the Fox Sports Net games on them....which include the standard 11:30am Big 12 game.
