With the right software, you can record encrypted channels in MythTV.
The smartcard gets plugged into a card reader and used to produce
decrypted channels on dvbloopback virtual tuners that mythbackend can
record from.  So it would be a very bad idea to just get MythTV to
automatically drop any channel that is encrypted.
