Last time yes, but that does not happen anymore on my set-top-box, maybe 
the software in the set-top-box
has been updated or the streams was using both old and new crypto.

For the last month the set-top-box has worked without problems, except 
that it sometimes takes a noticeably
more time to tune to a new channel that usual.

Another thing I noticed is that when the cam complains about 'No right' 
the cam seem to stops and MythTV
does a new Init. After that the channel is working.

I'm thinking of doing a hack and try to reset the cam if I get a 'No 
right' menu to see if that helps.
Is there an easy way to do that?
