Well, I've tested it some more now but I'm still unable to get the 
decryption going. Free channels work nicely and I get data from 
scrambled channels too but it's not getting descrambled :(

I've only tested this with MythTV. Since I'm currently not in front of 
the machine, the best I can do for now is try to get a recording going. 
This is what I get in the log:

The CAM keeps getting resetted, as can also be seen in this dmesg log:

I don't know if it's related but the Myth backend abends pretty often 
while trying to record scrambled channels. No log message or anything, 
it just dies... :-(

Obviously the recordings don't work, the files stay at 0 kb.

Is there some lower level tool to test the decryption so I can make sure 
this is not some MythTV bug?

Any ideas?
