A little more info on this:  when I try to tune an analog station 
(2->99), I get nothing but snow.  Any station via DVB (i.e OTA HD 
stations) give me the "You should have gotten a channel lock by now" 
error message.  The same kernel error messages seen above are shown in 
/var/log/messages.

Any ideas?
