That won't work. Currently, each video source must have a unique lineup
The patch at http://svn.mythtv.org/trac/ticket/3299 will allow you to
use a single ("meta") lineup for multiple video sources. However,
before it's integrated into mythfilldatabase, mfdb should be modified to
notice that multiple sources use the same lineup and cache the
downloaded listings data.
When the patch is applied in its current state, mfdb will download the
exact same data for the meta-lineup once for each video source that uses
the lineup. Therefore, applying the patch to "upstream" without
modifying mfdb to allow caching means that for a user with 2 "cable"
sources, instead of downloading two "smaller" lineups, the lineups would
be combined into one larger lineup, which would be downloaded twice.
(Granted, it's likely that one lineup is basic cable and the other
includes basic cable and more, so one is a larger lineup and one is
smaller, but 1+1/2 or 1+1/3 is still smaller than 1+1.)
Because of this, Robert's XMLTV-based approach (with caching -
http://www.gossamer-threads.com/lists/mythtv/users/283058#283058 ) is
currently the preferred approach. And, Robert's approach will work for
0.20-fixes users as well as trunk users, regardless of whether they
compile themselves or use packages.
