One thing that is not clear to me yet after reading specs from variou
TV Tuner cards is whether these cards can access the cable company'
channels above the analog 125 channels, whether they are HDT
channels or not

Some of these cards' specs seem to talk about being able to receiv
HDTV channels broadcast through the air, which has nothing to do wit
the numerous digital channels which are transmitted through the coa
cable, but are above channel 125
Can anyone clear this up
If they cannot display these 125+ channels, why is this

On a Google search, this web site had a "PC TV" section which talke
about tuners, but I cannot find that section when accessing this we
site

No you need a cable or satellite box in between signal and tv tuner. The
reason is because they are all encrypted digital channels and your tuner
card can only see unencrypted analog signals. The only exception to this is
the OTA HDTV channels which cards like the ATI HDTV Wonder is able to see
because they are sent unencrypted.

You might want to take a walk to www.thegreenbutton.com/community which has
a lot of info.

Are you certain that all of the super-125 digital cable coax channel
are encrypted ? Show me a URL which says this
Why would the cable companies be determined to prevent people fro
watching channels which are not premium channel

I'm assuming that you're talking about US standards--elsewhere in the world
the standards are different as are the tuners. The tuners have the same
limitations as all other commercial TV tuners. They can't in general
decode the cable company's digital content. There is a specific exception
if the cable company is providing unencrypted HD content in the QAM format,
in which case _some_ of the HD boards can capture it.
