Some areas in Cox New England do not use Copy Protection very widely, (Most Cox markets do use it on every channel except locals)
However, all the Premium Channels should use Copy Protection and be set to Copy Once, HBO, SHO, Cinemax, Starz maybe Epix and Encore.
No Copy Protecton is CCI: 0x00
Copy Once is CCI: 0x02
Regardless Val: V is the correct setting
See the following, even though it is TiVo, it is the same for all CableCARDs
