Yeah they had me reset the box which did not help at all.
They are sending out a technician on Thursday which wont fix anything. Cablevision so far has had about 4 events in 3D and I've been able to watch NONE of them because everytime its the same thing. They send technicians out who are clueless and don't know anything and nothing gets fixed.
Tennis Channel has apparently been pulled from Cablevision and Verizon FIOS. They apparently have not agreed to the new contract that required it to be rolled out to the basic tier. I believe Frontier FIOS previously pulled it.
Not sure if Tennis Channel was providing the 3d feed or not.
