Good thing too because they had no more in stock they were going to have to order one.Thank goodness that one worked. So I exchanged that one and the 7th worked.
But the two new cards and the 2 hdhomeruns would not work. After 2 bad cards I bought a second hdhomerun just to be sure. The Cablecards came from a Comcast office. The first 4 cable cards I got did not work and it was not the hdhomerun. I'm not sure about other providers but Comcast seems bad about cablecard support.
