Ok, I'll add it to my too long TODO list. I will start with converting 
the CI messages to VERBOSE macros.

Live-TV doesn't die on unencryptable channels but it would be nice to 
show a message that the channel can't be decrypted.

Basicly the same problem as 1. The CI/CAM spec EN50221 has unfortunately 
no reliable way to check if a stream can be decrypted. So we have to 
send the PMT to the CAM and check if the the data comes unencrypted 
from the card.
