 Problem with the channel scanner in the following case:
 QAM 256  - Cable high IRC.
 All QAM channels are broadcasted with the same ATSC Major - ATSC Minor
 combination. (1008-0)

 Result:
 Channel scanner picks first channel, inserts it to the db.
 Channel scanner picks up subsequent channels and run an update script on
 previously inserted channel.
 End up having 1 QAM channel instead of 23.

 Workaround:
 took mysql query log file and transformed "update" queries into "insert"
 queries.
 ran the scripts to have the channels in the db.

 Proposed solution:
 use the frequency and multiplex to isolate a channel and not just ATSC
 major-minor.
