Unfortunately unless you already own a Diablo CAM and your receiver has a CI Slot (and is compatible with the Diablo CAM), its probably not worth investing in buying one to try.
Because the Diablo opens SSR/SRG Swiss package at 13E using EMULATION of its Viaccess 2.6 Card (presumable imbedded non-public keys). (if you own a diablo current diablo firmware exists to open SSR/SRG Swiss in Via2.6)
I do not know if official newer cards are supported by your receiver/Diablo CAM (or even Viaccess CAMs, but would assume so), because I don't own official card.
But new cards are Viaccess 5.0 (and 4.0 cards exist), so Via2.6 will (more than likely as mentioned earlier in this thread) prob end soon, as will Diablo Emulation, unless Duolabs or 3rd party offer up new Diablo firmware (and there hasn't been anything new Emulation wise except C/S* on the Diablo CAMs for quite some time).
*C/S = Card Sharing. It may be possible to add this to your receiver via Fausto or other methods anyway.
