 - Encrypted channels can now be selected even without knowing the PNR (however, it
   is still necessary for the EPG info).

 - Fixed 'Transfer Mode' in cases where a non-primary interface was switched to
   a channel that only the primary interface can receive (which could happen in
   the EPG scanner).
 - The EPG scanner now starts with the first channel (it used to start with the
   second channel).
