Are you looking for little baseball fix? If so, tune to Comcast Digital channel 412 or DirecTV channel 213. MLB Network is now broadcasting there in preparation for its official launch on New Year's Day. The programming is all pre-recorded, including season retrospectives for the most part.
I heard a while back that MLB worked out a deal to be carried on basic cable, but it appears that MLB Network will stay on 412 with the three sports networks (NBA TV, NFL Network, NHL Network) as part of the digital sports tier. DirecTV will carry HD broadcasts, while no Comcast appears to be a no go for now. MLBN is scheduled to broadcast Thursday night games and the World Baseball Classic.
