No, he's asking if D* Active service will be working on the R15 by the start of NFL ST this fall as he wants to use it for the enhanced ST channels. I wish I could answer that, but I do not know right now when Active service will be implemented on the R15.
BTW, NFL ST enhanced games were the first four or five channels in ST. If you had a D10 or D11, you could get the "L" wrap with the scores of other games and stats by pressing the red button on the remote. Those without D* Active-equipped receivers would not see the L-wraps.
