My guess is he's looking for a card without a tuner (to save money,
perhaps?). If so, you'll be hard pressed to find one. An NTSC/PAL/SECAM
(i.e. analog) tuner is extremely inexpensive these days (reference all
the frame-grabber-type tuner cards for less than $30--including
manufacturer and retailer markup and all the other required components
of a frame grabber). Therefore, even if a manufacturer decided to make a
card without a tuner, the manufacturing cost would be nearly identical
to that of a card with a tuner, so the manufacturers all include tuners
as well as S-Video and/or Composite inputs. Doing so makes the marketing
guys' jobs easier.
/me steps on soapbox
Note that the same does not apply for digital tuners. The estimates of
the cost of adding a digital tuner to a device vary widely. For example,
the FCC estimates that by the time their "all digital tuners" mandate
comes into force (2007), the requirement to include a digital tuner will
add about $16 to the cost of a new set. Consumer electronics makers
disagree: they estimate its cost will be significantly higher. Depending
on which maker you ask, you'll get claims of cost increases from $50 to
$100 ( http://www.washingtonpost.com/ac2/wp-dyn/A61752-2002Aug8 ), to
$250 ( http://www.wired.com/news/digiwood/0,1412,54426,00.html and
http://www.guidetohometheater.com/news/11362/ and
http://www.cato.org/dailys/08-20-02.html ), or, from the mouth of the
Consumer Electronics Association itself, "hundreds of dollars" (
http://www.ce.org/publications/vision/2001/mayjun/p07.asp?bc=dept&department_id=5
).
To make matters worse, the FCC is taking a phased approach to
implementing the law (

Screen Size Deadline
36" + 50% of all manufacturers’ products by July 1, 2004; 100% by July
1, 2005
25" to 35" 50% of all manufacturers’ products by July 1, 2005; 100% by
July 1, 2006
13" to 24" 100% by July 1, 2007
Since the first thing 85% of US households do when they purchase a new
TV is disable its tuner (because they're using inputs from cable or
satellite boxes), you've got to love the idea of spending money (even if
it is "only" $16, that's enough for a pretty nice meal at a restaurant)
on something you don't want or need. Even with these "over-the-air"
digital tuners, consumers will still need to use cable or satellite
boxes to receive programming from a cable or satellite company.
