Basically, something like this:
- make sure your schedule source (zap2it?) has an appropriate channel
lineup for the new card (does your current lineup include digital and
analog?) I find it easier to maintain a different lineup for
ATSC/digital and NTSC/SD, as it means not having to use the channel
editor; possible downside is that Myth won't understand that ABC 7.1
shows the same content as ABC analog 7, etc.

- shut down mythbackend and mysql
