My intent is getting one MythTV box working, having two to experiment 
with as I go, and only slowly finding correct documentation for my 
system(s). Over the weeks I've had different blockages preventing me 
from getting very far. When I was using 0.26 the system wouldn't connect 
to SchedulesDirect, and no one could explain why. When  I switched to 
0.27 that problem went away. Meanwhile I was also trying to solve an 
issue with HD video where there was jerkiness and out of sync sound. 
That went away when I was finally able to use MythTV for playback, 
instead of VLC Media Player or Totem Movie Player. Now that I have a 
functioning system hooked up to the TV in the living room I'm able to 
continue my learning there and won't need to run MythTV on a second machine.

I don't plan to store lots of video for extended periods of time. Our 
habit is to pick a handful of shows to record throughout the week, watch 
them, and then delete them. We have only the one TV, so I don't see the 
need for multiple front ends or back ends. We do have occasions where we 
want to record two programs that are scheduled at the same time. So 
multiple tuners are helpful.

I haven't found documentation that spells out how MythTV is supposed to 
work at a higher level. I have found documentation about details, but I 
haven't read enough of them to see the larger picture. I am learning 
quite a bit more about the larger picture just by following the posts on 
this list, so I expect my high level picture will one day appear. You 
could think of my knowledge as a jig saw puzzle where I almost have all 
the edge pieces assembled, and have various areas in the middle put 
together, but still don't know which of those groups goes where. But, I 
enjoy jig saw puzzles, and one day I'll see enough of the whole picture 
so it starts to really make sense.

I'm sure it's not the fault of the writers of the documentation -- 
because there are so many different distros out there where things are 
done differently -- but often I find definitive instructions that just 
don't work when I try them. After nosing about I eventually discover 
that, "Oh. On Ubuntu it's in this directory." The writer of the 
documentation must be using a different distro.

I'd better stop now before I get to rambling more than I already have. I 
will post more questions as they come up, but I'll do them in individual 
threads. Over the years learning Linux I've discovered that giving 
thought to a e-mail subject line is almost as important as the question 
being posed.

Thanks for asking each other all these questions. I'm learning a lot 
just reading them.
