The strong 8000 is Holland version with emmbeded SECA decoder The card is PCB-Card (DIL) 24c16 16f84 (pirate) In Info menu i can see decoder version is 15 It makes (black screen and no sound) most on Spanish and French channel, I'm not shure is it makes to Holland channels, but some weeks ago I've seen in newsgroup 3-4 questions like mine from Strong 8000 owners.
several weeks ago Canal+ started aggressively defending themselves from the pirates. They sent out false key updates and all kinds of stuff which knocked out a lot of cards - particularly those used in embedded CAMs.
Try reprogramming your card with the latest software, preferably with fixed keys (no autoupdate). Or have you already done that? 2old
