I don't use ntop, so I'm not sure how it's determining "MythTV" as the
source. But, to eliminate a lot of variables, I would use a simpler tool
for a lower level view. From a terminal session run:
sudo netstat -anp |grep $PORTNUMBER
Where $PORTNUMBER is one of the ports from connection you're looking for.
Or, use the destination IP address. Either way it should show which
process is talking.
