Basically, you need one tuner per viewer for LiveTV.
If, however, your viewers communicate with one another, and you realize
that multiple people want to watch the same show, they should record the
show. Then, each viewer could--using his/her frontend--start watching
the show (from the recordings section, not from LiveTV) any time he/she
desires (even while the show is still recording--starting from the
moment the recording starts until it's deleted--even while other viewers
are watching the same show) and Myth is only using one tuner to record
it regardless of the number of viewers.
So using LiveTV hogs a tuner while recordings don't.
If you're interested why LiveTV consumes a whole tuner, try to come up
with an algorithm for maintaining an X megabyte ring buffer with
multiple people watching the same channel from the same tuner.
Depending on how much pausing is going on, it's quite possible that the
person who's closest to real time is more than X megabytes ahead of the
person who paused LiveTV to go make some dinner. So, it's quite easy to
go beyond the allowed limit for the buffer to ensure each person has
his/her fair share of rewindability.
And, then again, there's the whole, "If my list of recorded shows isn't
more appealing than the things that just happen to be on now, then I
know I'm not using the DVR properly" perspective (to quote Bruce J.
Markey). Basically, once you get used to the DVR, you'll likely record
anything and everything you might possibly want to watch. This also has
the benefit that (much to Jamie Kellner's horror), you don't have to
watch/wait for the commercials (even while it's recording thanks to
Chris Pinkham's near-real-time commercial flagging). Not to mention you
can playback at faster than real-time and watch the show in
significantly less time with no losses (1.75X!!! Thanks Mark Spieth!).
But, then again, not everyone is a DVR convert like me.
