So what are your CAMs CAS settings & CONFIG settings?
Are you using any cards in the CAM? What version of Diablo CAM are you using? What version of Ipnosys or Underworld is installed on it?
And are you using any other patches? (ie is your receiver patched?).
CAS:
all off except for
SECA [ON] for Seca RAI card
although VIACCESS [ON] for imbedded keys will not cause issue
CONFIG:
Language [as appropriate]
Caids [MAIN] or any with CaID 0500 (Viaccess) for Canal Sat ID 022610 but not the [CAIDS] file that comes with Ipnosys/Underworld.
Auto PMT [OFF]
Emulators [ON]
SmartCard Mess. [Show Normal]
Both MTV Pulse, Idol, France, VH1 Classic, ESPN America etc etc, Working fine here with IPNOSYS 0.35 on both my Diablo Light v2's (Rev3.9 & 4.0) with my latest key.bin.
(although these Canal Sat keys are imbedded in the firmware, so keys are not in the key.bin)
