Myth scans the channels in numeric order.  It will start with '0', 
regardless of the program id on the channel.

In your example - it found information for the first program on channel 
83 - mapped it to NBC...for what ever reason, it did not get info on the 
second two, so it added them as 83#1 and 83#2.

If there was no information on channel 83, but, three programs, it would 
add them as 83#0, 83#1 and 83#2

For the unnamed ones, you need to go through a process of identifying 
them, and changing the channum, callsign, description, xmltivid and freq .
