Version 1.4.7 simply switched to the encrypted channel and didn't check
whether it was actually decrypted.
Version 1.5 automatically selects a suitable CAM, and if there is more
than one CAM that claims to be able to decrypt a given channel, it needs
to check whether it actually can do so. Therefore it starts in Transfer-Mode,
which is apparently a problem on FF cards with high bandwith channels.
Too bad the CI standard is so broken...
