Agreed, many options for directly grabbing the data.
However, most people don't care about minor analog stages. Audiophiles
and videophiles are not the primary consumers of this stuff, as
evidenced by the mountains of MP3s not even sampled as well as they
could be (64 kbps being the norm) and by the DIVX files shipped around
the Web. And videos 10x-compressed to fit on CD-Rs. The people
bootlegging CDs and DVDs are not usually the people with the 40-inch
plasma screens.
Video pirates in Asia routinely use covert camcorders to grab weird-ass
angles of first-run movies. And their DVD stall customers cheerfully
pay them the equivalent of two dollars for their DVDs. Compared to
this, sampling from an analog signal is heaven.
I have my own collection of about 30 DVD+Rs, each containing 1-2
full-length videos. By the end of this year, I should have several
hundred movies added to my collection.
The video quality is perfectly fine for me, and I like good quality.
Until I move to HDTV and blue ray DVD, the quality is excellent. And
even with HDTV and blue ray, so long as component video connections (a
la progressive scan cables) are available, nearly perfect sampling will
still be easy to do.
(Which is why Hollywood would like the HDTV sets to be sealed, with
only digital inputs. Except that they tried this trick with twiddling
with the specs of past HD generations. A lot of HDTV receivers and
monitors are already out there, and changing the spec yet again and
making the suckers, er, "early adopters," have to scrap their systems
is not going to go over very well.)

Indeed.

Friends,
After more than 7 years with my got.net e-mail address,
"tcmay at got.net", the amount of unsolicited e-mail I am getting on a
daily basis has escalated sharply in recent months.
So my new address is "timcmay at got.net"
Please make a note of it and change your address books...if you wish to
reach me in the future! Mail to my old address will be forwarded to my
new adress for a few weeks, but then will start bouncing.
P.S. I plan to make strong efforts to stop my new address from being
harvested by spammers, such as using "timcmay at got.removethis.net" in
Usenet posts. I hope this works.
