[mythtv-users] Zap2it and rebroadcast cable

Configure tv_grab_na to use the original provider (ie the one with all
the channels and more).  Then edit your tv_grab_na.conf and add "not "
before the channels that you don't actually receive.  Finally,
go into your database and edit the channels table so that the "chanid"
column matches Zap2it's idea of the channel number (plus 1000*n for
the card number), and the "channum" column matches what you actually
see on your TV.  For example, I have:

> select chanid, channum from channels;
+--------+---------+
| chanid | channum |
+--------+---------+
|   2006 | 5       |
|   2008 | 6       |
|   2009 | 2       |
|   2010 | 10      |
...

which means that what Zap2it says the satellite is broadcasting on
channel 6 shows up at my college on channel 5, etc.
