Yes. a MythTV Video Source is the list of channels that are tunable (and
usable) by a particular input and their tuning information. A Schedules
Direct lineup is just a list of channels and their tuning information.
You can have a single SD lineup shared by multiple MythTV Video Sources
(with each having either different tuning information--i.e. same
channels, but tuned by one source using HDHR Prime to request the
channel by number and tuned by another source using HD-PVR's external
channel change script--or even having a different subset of the channels
in the lineup--i.e. for ClearQAM vs HD-PVR). A single Video Source,
however, can't use multiple SD lineups.
The best approach if you do need to use listings data from multiple
lineups in a single Video Source is to create a wrapper script for
mythfilldatabase that uses tv_grab_na_dd --dd-data (do not use --output)
to get the raw (DataDirect format, not XMLTV format) listings data and
then use mythfilldatabase --dd-file to load the listings for each
lineup. Make sure you don't use mythfilldatabase --file (do not use
XMLTV format data) or you will break your data and will be missing some
data.
