Make a backup of the mythconverg database.
Make a separate backup of the cardinput, capturecard, dtv_multiplex and
Then delete all your cards and sources and start again in mythtv-setup.
Confirm that cardinput, capturecard, dtv_multiplex and channel tables
When you get to 3> Input Connections, assign the source to your
HDhomeRun, and do a channel scan using your HDHR. Make sure NOT to check
the 'Unencrypted Channels' box. This worked for me recently (hat tip to
JW. for the pointer). You do end up with a channel table containing
entries for EVERY digital stream, however. I had 454. Then you have to
check every channel to find the ones you can actually receive...very boring.
Between cable co's. changing how they transmit channels, and something
going on with the scanner, cards are being set up improperly, in part
because the scanner is being given garbage by the cableco. For example
it appears that Rogers Cable in Toronto is marking all channels as
encrypted... So a 'Unencrypted' only scan gets nothing and an
'Encrypted' scan gets every stream, but not necessarily correctly.
It is unconfirmed but I think that certain settings in capturecard and
cardinput get set wrongly too, if you do an 'Unencrypted' scan.
Keep your backups please. They may be useful to those who actually
understand how the code works.
