No.  All tuners on a source have to be able to receive all channels on
that source.

Channel numbers are whatever you want them to be.  They are used for
the user interface only.  Internally, a channel is identified by its
chanid value, not the channel number.

For scheduling, the callsign is what is used to match channels - so if
you can receive the same channel on two different sources, you can use
the same callsign on both sources and the scheduler will decide which
one to use when, based on the priority settings.  I think channels
with the same callsign can have different channel numbers, so that you
can select them separately from the user interface.  But I have never
actually done that.

Yes, it is hard to argue with success!  It looks like MythTV can
handle that sort of .m3u file just fine.  I have not been actually
using the IPTV tuners for real Internet based IPTV, just to talk to
minisatip for my pay satellite channels.  So I have never encountered
the chunked setup that seems to be used for HLS encoded IPTV.
