Hello,

I was reading http://www.hot-deals.org/hdtv/2/#How.Does.HDTV.Compare.to.DVD and read the section
that said "If you have a HDTV PCI Card for a PC, you will only be able to record HDTV channels."

I am worried about this since I am getting a HDTV tuner for my PC and going to use the over the
air (OTA) with a cheap indoor antenna. Does this mean I will not be able to watch non-HDTV shows
on TV channels that support HDTV (e.g., ABC, CBS, NBC, FOX, etc.)? I believe all TV stations I
get via analog are not missing in listings I saw for HDTV.

Thank you in advance. :)

Well I was thinking of getting one myself. I do not like the fact that
consumer electronis tuners cost so much to do so little. I was going to buy
this http://www.fusionhdtv.co.kr/eng/Products/HDTV5usb.aspx and hook it up
to my PC to record shows, and then get an X-Box 360 and (hopefully) hook it
up to that and have that serve as my HD tuner for my TV!

The main reason I was looking into these was because my Nividia video
capture WDM drivers suck. I cannot capture all of the time as the drivers
do not always work. Especially with the latest Geforce driver. I see blank
screens on prgrams that detect the driver and the only program that shows a
picture is the Windows Movie Maker. I obviously do not want to capture in
AVI, so this looks like a great product, although I wish it cost less. It
also captures in progressive.

So what is the reason for lack of compression hardware? That it is too
expensive? As long as compression only needs to be done for analog SD,
which should be the case if the PC gets already-compressed ATSC into the
PCI bus, it should not be that expensive, and should not be that hard to
do in software (e.g. the PCI bus does have sufficient bandwidth for raw
uncompressed SD video).

Still, in a world where everyone chooses based on price, tossing out as
many features as possible to get the price at the lowest point does tend
to be the modus operandi of consumer product design.

If it could do the job in 18% of CPU in the fastest available (today)
Intel CPU, and match the quality and effectiveness of real hardware
compression, I'd be interested in that software.

I've been doing some compression of multitudes of weather satellite and
radar image files into DV format with free DV compression software, and
it takes about 1/3 second to 1/2 second per frame to compress at 800 MHz,
so it would take on the order of 8 GHz to achieve live compression using
the coding they have (libdv).

Hardware compression can, conceivably, do a number of the DCTs in parallel
to achieve greater throughput.
