Mythfilldatabase will try to match up shows where it can, but for most
channels, you will have to go in and manually set a XMLID. Go onto your
SD account, open up your digital listing, and mouse-over a channel to
get its ID. Then, apply it to the channel either in the mythtv-setup
channel editor, or in the editor in mythweb. You should go back through
the ones that have data, and confirm that the XMLIDs were applied properly.

Do you have your recordings set to only record on a specific channel?
Since you're using separate lineups for analog and digital (as you
should), the analog version and the digital version are seen by MythTV
as two independent channels.

As above, you will have to tell it to record from any channel, or from

MythTV only knows what the cable company tells it. With digital TV, you
have several channels within a single frequency band. If the cableco
doesn't tell myth what the channels are, myth will define them based off
the frequency. While Sprout may be cable channel 119 on the lineup, HSN
is on frequency 119. As mentioned above, check the channels against
their given XMLIDs and make sure they match up.
