Oh, I should say that alternatively, you can just change the XMLTV IDs 
for all the existing channels on the original Video Source to those used 
by the new listings source/EPG provider.  Since those channels were 
properly scanned, they have the appropriate information, so you can keep 
using them and just swap the listings source.
