Hi all.  My cable provider dropped their analog channels and went digital.

This is over cable (not dish).  I figured this would be a good time to
upgrade to 0.24.

I have an HVR-1250.  Myth see's it, and I ran the scan for channels
thing in mythtv-setup, and it found lots of channels.  I can go to
live tv and they come in fine.

There are three channels, 11_1, 11_2 and 11_3 that kinda seem to get
EIT data.  Nothing else does.

I have searched, but info seems scattered and old.  One person says
"set sistandard to dib" while another says "atsc channels should never
be dib"  (or something like that).

my dtv_multiplex table has no networkid's.  Some say you have to have
transportid's (which I have) and networkid's (which I dont).  But they
say its cuz they imported channel.conf and you need to do a full scan
in myth, which is what I did in the first place.

I saw references to "dvbsnoop -s pidscan".  dont know what a pid is,
but any time I ran it, it never found anything.  Have no idea if thats
ok or not.

Also, I added eit,siparser to my logging, and see things like:
