My experience has been that the MythTV scan will not find channels
that don't have PSIP data. On my cable system, all the local channels
are rebroadcast without modification, which includes the PSIP data.
MythTV finds these channels. There are several cable-only HD
channels which are broadcast without PSIP data, and MythTV does not
In these cases, I edited the channel data to point MythTV to the
frequencies where I knew the channels were. There was just another
post asking about this on the list. I'll post some mods for
mythweb to help with this, and some more info on the changes, as soon
as I can.
