Is the coax output on the Comcast cable box and analog cable passthrough, 
or is it labeled TV out?  If it is TV out is it outputting on channel 3 or 
channel 4?  You will need to set the channel to whatever channel the cable 
box outputs on.  If it is a passthrough I don't have any ideas for you 
except to try plugging the cable into the myth box directly skipping the 
cable box and seeing if you get anything with that.

HTH,
