I am confused too:) The error happens whichever card I try to select. I 
am aware of the cold boot problem. However, if I simply restore the 
backup database and restart the backend, without doing anything else at 
all Myth can tune using all three tuners. However, if I go into setup it 
claims it can't open any of them.
