When is DirecTV going to add/update the Big Ten Network overflow channels? BTN's website says they're 609/609-1, 611/611-1, 612/612-1 and 615/615-1. 623/623-1 and 625/625-1 aren't used any more according to them. I thought they'd add them today since its Wednesday but nothing. I better not miss any Big Ten games...
