Standalone = local broadcasts, unscrambled analog cable channels,

TiVo with DVD recorder = Standalone that can record programs
or groups of programs to a DVD. Certain models
can operate without a TiVo subscription. This
"Basic Service" is free but limited.
DirecTV combo units = satellite only, but has two tuners.
This is a TiVo recorder built inside of a DirecTV
receiver; product support comes from DirecTV instead
of from TiVo. Recording two shows at once is great.
HD DirecTiVo = High-definition DirecTV (two satellite tuners)
and local digital broadcast (two ATSC tuners).
Does not do analog broadcasts nor cable-TV.
A TiVo subscription is required for all but the ones that come
with Basic Service (or the older Series 1 units).

Another important distinction between Direct TV Tivos and the rest is that
DirectTivos record the satellite mpeg stream directly, there is no encoding
done in the unit. This means that there is no quality setting on a
DirectTivo, everything is recorded at best quality. Generally, DTivos
record a much better picture in a lot less space on the HD. A 80 hour
standalone Tivo may only get 30 hours at best quality, but an 80 hour Dtivo
gets about 80 hours at highest quality. The prime reason for this
difference is DTV can afford to buy top end mpeg encoders and do multipass
encoding of the video, standalones have to get by with a cheaper single-pass
encoder.

No, it means the recording will be done at the same quality as it was
transmitted. This does not mean "best" quality. Some programs are sent at
quite a compressed rate, enough that significant artifacts can crop-up from
time to time.

Again, not wrong but not entirely true. If you record a wide mix of content
it does seem to record "more" than a standalone unit might. But if you end
up recording a lot of stuff that's sent without as much compression (all
movies) it can easily slip to getting less than 80 hours. Nowhere near as
low as an SA unit on Best; more like around 50 hours.

Yes, DTV's equipment and expertise in managing the downlink bandwidth does
seem to do a better job overall.

Basically: Delay the video a few seconds and have one chip make a pass
on the video and send some information to a second processor in the
chain so it has a better idea of what to do.
See these results for more information:

[DirecTV could also do more advanced multipass encoding on PPV movies
since they have those long in advance of airing, but I have no clue if
they actually do this]

Do you know how DTV determines how much compression each channel uses? You
mention "movies". Do you mean PPV movies only? Do more popular channels get less
compression than less popular ones? Or do sports channels get less compression
to minimize motion artifacts? Are these consciously made decisions or are they
automated depending on the content of a particular channel at a particular time.

There are no SD channels on DirecTV with bitrates so high that an 80GB drive
would only record 50 hours. The highest bitrates are less than 3.5Mbps, and
those only show up for short times during high-motion sequences. The
average bitrate is 3Mbps or less for all SD channels, so around 65 hours is
the absolute worst case on an 80GB drive.
The reality is that most channels use far less than this, though, so it's
not uncommon to get more than 80 hours on an 80GB drive.

Yes it does, because you can't do any better than that. "Best" means the
best recording you can make of the signal, the fact that the signal may
already be degraded is not relevant. Since the Dtivos record the mpeg
stream directly you can't get any better, therefore it's the "best" quality
for the recording.

My recordings tend between about 700meg to 1.2gig per hour. Overall it
averages to about a gig an hour. Certainly far better than the 50 hours you
are claiming.

You're wrong but you're just arguing semantics, so it's not like it matters.

And I've had plenty of situations where movies were taking nearly 2gb/hr.
What I've discovered, however, is that enough programming on DTV repeats
itself often enough that I really don't bother 'saving' much for very long.
That and there's enough content from other programs to more than satisfy
most of my TV viewing interests. This learning curve seems to be something
a great many Tivo owners eventually discover. But usually long after they
get hung up on free space worries.

No, you haven't. DirecTV has never run any SD channels at over 4.5Mbps

Hey, you go with your anecdotal evidence and I'll go with mine. So please,
spare me the pissing match over it. When I first got my RCADVR49 DirecTivo
I can distincly recally it taking around 2gb/hour for certain recordings,
mostly HBO and PPV movies. I upgraded the drives to a pair of 120's and
stopped worrying about it.

They are deliberate decisions made by the network providers.
I wouldn't be surprised if they get cheaper rates for reducing
their VBR for part of the day.
One time, I was watching a "late late night" movie: Attack of the
50 Foot Centerfold. The variable bit rate was cranked down, way
down. Every time the photographer's flash went off, the screen
went completely white, and then took forever to get the details
back. Macroblocking was visible for almost a full second.
The VBR on HBO that same night was much higher; it had no visible
digital artifacts.

Again, you did not see this. You might have seen 3GB for the full movie
(about 1.5GB/hour), but they haven't had any bitrates that high in a *long*
time, and have never gone to bitrates as high as 4Mbps for *any* SD
channel, let alone the nearly 5Mbps that would be required for an hour
to take 2GB.
There are many, many people that monitor this on a regular basis and post
the results, and none of those support your 2GB/hour claim.

If your "old" drive is the original drive, it's pretty simple if you are
handy with putting hard drives into a PC.
Just put the drives in the PC, boot off of an MFS Tools CD-ROM, and then
issue the following command:
mfsbackup -Tao - /dev/hdc | mfsrestore -s 127 -xzpi - /dev/hda
This assumes the old drive is installed as secondary master, and the new
drive as primary master. For more info, see "UPGRADE CONFIGURATION #3" at:
http/www.newreleasesvideo.com/hinsdale-how-to/index9.html
It'll take a while, but it will preserve everything.

It's not all that easy. Instructions are here:

It's not all that hard either. It just involves pulling the drives from the
Tivo and using a PC to rearrange things. If you're comfortable with
upgrading a PC's hard drive then upgrading a tivo is just as easy.

Except the Hinsdale instructions can be confusing the first time through.

It's been a while since I had to look at them, but when I did, the main
problem with the Hinsdale instructions was their length. They describe
every possible permutation and complication short of being abducted by
aliens mid-process, which makes them lengthy. I suggest skimming them,
then reading them through with a highlight marker or something to mark the
parts that apply to you, then doing the job while referring to the parts
you've marked.
