DVB-S CI used by DVB-C?

[Kent.Nielsen at MicroLink.ee (Kent Nielsen)]

Hi,

I have a Technotrend Rev. 1.5 (FF) card, and also an internal CI (came
with Fujitsu-Siemens Rev. 1.3).
I will buy a Technotrend Budget C-1500 (DVB-C) without a CI.

I believe I can use first one as front end, but can I use first one's CI
to decrypt DVB-C channels (Conax).

Should it work?  Does anybody have similar setup?

Thanks in Advance,

Kent Nielsen
