Interesting, another rare game tonight where both teams broadcasts are local OTA. Spurs @ Mavericks game at 8:30PM ET tonight. Spurs broadcast is KMYS-TV "CW35" and the Mavericks is KTXA "TXA 21". According to the guide, D* will be using the Spurs Broadcast and it will be in HD for out-of-market LP subscribers.
It must have been a late change because iN DEMAND's schedule still lists FSSW-Dallas as the feed. I looked earlier in the week and the Mavericks schedule on their site still said FSSW as well, but I do see it has since been updated. According to DISH's schedule they will be airing the game in HD but no idea what teams broadcast they will be utilizing.
FSSW shouldn't have had it from the get go because it's high school football state championships weekend and FSSW carries them. Maybe they were thinking the Mavericks would be on the alternate FSSW channel.
P.S. Go Allen - on our way to 3-peat tonight and 43 straight wins!
