TBS3102 5 Crystal Phoenix Card Reader - scrambled channels

[nightshadow36]

Hello.

I have a paid for subscription sky card and I am useing the TBS3102 5 Crystal Phoenix Card Reader oscam and mumudvb.

With the TBS3102 5 Crystal Phoenix Card Reader it only decrypts 4 channels - if I try and do anymore I just get a black screen when useing VLC.

Is there a limit on how many channels it can read? is it only 4 at a time or am i doing something wrong.
Thank you.
