https://secure.wikimedia.org/wikipedia/en/wiki/North_American_cable_television_frequencies 
may be a good starting point. Channel 67 on your cable system could be 
at 483.00 MHz, which would then be a key for the "frequency" column of 
your dtv_multiplex table. From there, cross-reference the "mplexid" and 
then move to the channel table. Update your PBS HD station's mplexid to 
match channel 67's location and update the "serviceid" to 1.

That may take care of it or at least get close.
