Removing the visible flag with mythweb is the fastest way to prevent
channels from being tuned, and it has the advantage of being easily
reversed.  Removing the channel from your lineup on  SchedulesDirect (if
you use it) will prevent the guide data from being downloaded, so I often
do both to speed up the mythfilldatabase process.

I use QAM and had to scan for channels and link the xmlid's manually... if
your channels were created based purely upon your schedulesdirect listings,
then just editing the channels there may be adequate.
