I gotta give props to speedkilz88 on this one.. he came up with the info.. i grabbed it from another thread, but i tried it and it is gonna work, so i thought it deserved its own thread.. here's what you do:

download the tvuplayer.. then when the player comes up, choose the 10018 CBS station.. right now, it is playing a kids show called "LazyTown", which is correct according to the station's official website program listings, which shows the Cowboys game also..
