Comment:

 Err, no, definitely not.  The HRC and IRC channels are offset from the
 normal values; the frequencies used by MythTV for regular cable are
 completely incorrect; because they cover the right range, you get all the
 channels, but with the wrong channel numbers.

 The chart I pointed to give the standard EIA-542 frequencies; add 1.75 to
 the video carrier to get the center.  You can also look at the frequencies
 used by the linuxtv project in their dvb-apps application

 linuxtv-dvb-apps-1.1.1/util/scan/atsc/us-Cable-Standard-center-
 frequencies-QAM256
