Having this problem all the time (but not every time :) ). Channels are 
probably still encrypted while Myth tries to put them on screen.
A longer "grace period" before displaying the error message would be 
nice for my setup, but as it only seemed to affect me, and only while 
viewing live TV, I decided not to dig in to it.
