I have noticed that the Astros games this year are being shown on FSN Houston, instead of FSN Southwest. FSN Southwest has always been broken up into north and south territories, with Dallas teams showing in the north and Houston or San Antonio teams showing in the south. However, it was all just FSN Southwest. If there was a programming conflict because of territorial restrictions, one of the games was shown on the primary FSN Southwest channel (D* 643) and the other was shown on the alternate (D* 646). I know that the Rockets and Astros were discussing leaving FSN and forming their own Houston-based RSN. The Rockets even left FSN for one season a couple of years ago, but came back. I wonder if this is a first step in splitting FSN Southwest into FSN Dallas, FSN Houston, and FSN San Antonio?
