That's good, but it actually overdoes it.  One of my first bad
Myth experiences -- once it was working -- involved it failing
to record a show because the signal wasn't strong enough.  It was
convinced, even though it had failed, that it had recorded the
show.  It took quite a bit of work (and I lost several minutes of
the show) trying to convince it to record it "again."

These things will improve with time.

I am sure the suggestion concept will see much advancement over
time, including showing you shows that people with similar tastes
to you are approving of etc.   With disk space cheap you might also
just automatically record new shows and specials until the word gets
out over whether they were good or bad.

In fact, this is similar to how I use the PVR.

See the section at the bottom called "Quick Review and the Nature of TV..."

The interesting concept of the suggestions was that, since the Tivo
has an mpeg encoder, there is no reason for it to not always be
recording something into spare disk space.  Why not?  It's a new lens
onto the world of TV and worth exploring.   As long as you have
a clear concept of spare disk space, and your recording doesn't cost
you CPU, you should go for it.

Don't worry, you will get over it. :-)

I mean I used to watch Survivor religiously.  It was the only show I
watched live (Starting at 8:15 and ending live.  I never watch LIVE-live).
But I broke from it this season and find I don't really miss it.

I sort of view that if I want to adopt a new show, I must drop an
old one.  Of course, my view is I'm watching too much TV.  Not
everybody views it that way.   But it's good to have my tech make
this easier to do, not harder.

Right.  This is what Tivo does and it's bad.  You should almost never
have to use it, because the auto padding should be long enough to handle
almost all cases.   The only time you should need to use manual padding
is if you have two shows that abut, and they don't follow their time
slots in some predictable way, and you don't have enough tuners and you
know just what you want.  That's pretty rare, but it does happen.

That's the right approach -- but it should also start the playing cursor
at the listed start time, and allow rewind if needed, so the user isn't
even aware of it most of the time.

Though most users won't really get into that.  One imagines that a good
idea would be for users to form collective opinions on shows.  For
example, the last 5 minutes of 60 minutes are all commercials.  The
last 30 seconds of Survivor are an important part of the show (final words
of contestant.)   The first 30 seconds of some shows are always the
theme music (less common today than it used to be.)  Etc. etc.

A database of this would be very handy so people would almost never
have to manually pad.  True PVR success means "it just works."  You don't
have to tweak it.  Because my mother would not ever tweak it.

Yes, the better answer is more disk.  However, my point is that if
you are waiting a long time with a show it's probably not a big sporting
event.  For me the killer lost-endings of sports and events have
been watching them that very day, or a day later at worst.
