Channel change script is defined per capture card--specifically so you
don't have to create separate Video Sources for the same source of TV.

Just set up a different script for each capture card or--assuming the
script you're using accepts the "blaster number" before the channel
number--change your external channel change script for each capture card to:
and let MythTV stick the channel number on the end after that.
