I am sorry to hear that... Unfortunately for me, I can't consider a cam

which can be programmed for NDS-Videoguard for sky italy.

But in all receiver I tried, my cam worked well, except for my nova card :-(

Do yiu think, like Andrew suggested, that using a full featured card 
(like the nexus-S one) could be a solution?
