There is a manual way, although I don't think it's very tidy. Do your 
channel scan as usual in mythtv-setup, then go to channel editor -> 
transport editor. Once in there, if you can figure out which is which, 
you can highlight the dvb multiplexes you don't want and press 'D' to 
get rid of them. Doing this also removes the channels associated with 
those multiplexes.
