Hi Nick,

Actually, it doesn't matter - mythfilldatabase will just reject items in 
the dvb scrape that are not in the channel list - specifically, it uses 
the xmltvid to do this - just make sure your xmltvid in the channel 
table matches the entries you get from the guide, and it will do the 
rest for you.


Cheers,

Richie
