It's purely XMLTV ID.  Therefore, if you have the right XMLTV ID on the 
new channel, you likely have another channel in MythTV defined to use 
the same XMLTV ID.  mythfilldatabase will only put data into the first 
channel it finds with that XMLTV ID.

That won't affect anything.  It's just an internal identifier used by 
MythTV for channels.
