Thats good to hear!

Hmm, if you find you don't get any data with the CAM inserted, perhaps that 
CAM is slightly nonstandard... because as you can see from the list, other 
people are getting data with CAMs inserted.

CAMs are meant to pass the transport stream straight through from the start, 
but perhaps that one does not do this until you tell it to actually decrypt 
something... anyway, let me know how it goes.. If I have the time later, I'll 
have a play with that CAM myself..
