Best approach is to clear out all the channel information (and all the 
other related, but not in channel table information) by doing the Video 
Sources portion of 
http://www.gossamer-threads.com/lists/mythtv/users/264034#264034 , and 
then re-create the Video Source, re-connect inputs, then re-scan (or 
fetch) channels. Just make sure if you scan for channels, you set the 
xmltvids before running mythfilldatabase.
