Mostly. Also, some features that TiVo doesn't have, or only
makes available on certain models.

No, running a web site requires running a web server. Apache is
a good choice. If Comcast is blocking inbound port 80, you can
set it on port 81 or 8080 or 16300...

Yes; you'll need two tuners for that.

Yes, but it's a computer. I think the best supported of these is
the MVPMC, but I don't use one.

The PVR-250 doesn't get you anything over the PVR-150, which is
cheaper. A PVR-500 is a pair of 150s on a single card. I use a
PVR-500 and an HDHomeRun, which is a pair of HDTV tuners in an

I'm not sure why these two sentences are connected.

No, just playback at each TV.

Well, there's the MVPMC. There's the X-Box Media Center, and
older X-Boxes running Myth's frontend on Linux. And dedicated
MythTV machines can be set to power themselves down when not in

I don't think anyone is currently shipping such a decoder card.
However, pretty much any modern laptop, or one with an NVidia
5200 or later video chipset, will do a decent job decoding by

1. Doesn't have to be loud.
2. Doesn't have to be right next to the TV -- cables come in a
variety of lengths.

With a splitter, of course. They are cheap. My house currently
has eight cable devices of various sorts, and I'm in no way

No, but you do need separate tuners for HD service. There is a
thread about cheap ones right now.

Well, the 160GB TiVo is only $300, and you can add external
storage to that now.

Only the cards that do HD by themselves.

You can get as complex a remote as you want. Personally, I use a
$20 Sony remote
and some people use $200 Logitech Harmony remotes, and some
people use magic wands.
Read the MythTV HowTo section on keys. Anything that you can do,
you can do from a sufficiently complex remote.

Read the wiki.
Every time you give up a right, the terrorists win.
Tyranny is something that creeps up on you.
