Not sure if this is the same thing or not.. but my new HDTV has a tv guide
that appears to be different than the ATSC EIT that is sent on the HDTV
channels. I get tv guide info OTA for ALL stations in my area.. not just
HDTV ones.  The TV has to be 'off' in order for the tv guild to be updated.
I get a couple of weeks worth of guide info for all of the locast OTA stations
in my area.

Can  mythtv receive these tv guide type broadcast?
