What is a repeater? - An IR repeater has a sensor at
the TV and emitters on the other end. IR remotes require line
of sight which would be a problem for your installation to use
the IR remote that comes with the card. An IR repeater would
receive the IR signal downstairs and repeat the IR signal
upstairs. For your application I would forget the remote
control and use a wireless keyboard to control
everything.
Also, for the wireless keyboard,
would that need an IR receiver that would be connected to the
USB port on my computer? - The wireless keyboard I
recommended is a RF based unit so there is no line of sight IR
at all. Yes there is a RF receiver that plugs into a USB port
on your computer.
So, if I understand this right,
the MyHD program has software that would only be visible and
accessible from the TV screen, not from my computer screen...
Does that mean that each time I reboot my computer, that I
would have to reload the program from the TV? No big deal, I'm
just trying to understand. - Actually there is a
software interface that is available only from the TV screen,
but everything can also be controlled from the wireless
keyboard using the HDTV as the PC monitor via the pass through
connection. Maybe that was not made clear. In your case most of
the Vizio flat panels can be used as a computer monitor
assuming the PC will output a compatible resolution. You didn't
mention the TV model by the way and to be sure of the
capabilities of the card, the exact manufacturer and model
number of the card would be needed, but that information should
be in the graphics card manual. So I would think that you could
use the pass through connection to allow your computer screen
to be put on the HDTV. Basically when you are watching TV, the
MyHD card will be supplying the video and when you are not
watching TV the computer display will be supplying the video.
You can switch back and forth from TV to computer via the
keyboard.
I'll look into the programs that you
listed so that I can understand them better. Would those
programs be accessible from the TV if it is connected using the
VGA port on the MyHD card? - Using the pass through
connection explained above, every thing the computer is capable
of would be accessible via the HDTV screen, so yes they of
course would.
What are the limitations of doing
something like buying a Hauppauge tuner card, using a long VGA
cable, buying the BeyondTV software and some extra RAM? - There
is nothing wrong with going that route if you are sure the
computer is capable of supporting that route. Again maybe the
point bigloww made was not clear. The MyHD card is a completely
self contained system and hardly uses the computer CPU at all
for any of the HDTV processing. The only thing the CPU is used
for with the MyHD card is launching and control of the MyHD
application, accepting the streamed video data from the card
and writing it to the hard drive and of course the recording
task scheduling. And there is a relatively small task of
creating the interface window on the computer display. But all
of the heavy lifting is done by the card, such as decoding and
video scaling and formatting. That is in contrast to the tuner
cards that are basically only tuners. Those cards deliver the
streamed data to the CPU not only for recording but for
decoding as well. Some video cards will have the necessary
decoders on them and I would imagine that your card would, but
the beauty of the MyHD card is you can be assured that
practically any computer will fully support it. As an example,
I had one of my MyHD cards in a 900 MHz AMD computer with 512
MB of memory and it never missed a beat. My HP media center PC,
which is a 3.0 GHz dual core, came with a ATI HDTV wonder card
and it skips on ABC and FOX, both who transmit at 720p/60. I
assume it is because of the high frame rate, but my MyHD card
never misses a beat.
As far as the friendliness
of those other software packages, they are more user friendly
and are simpler to operate. Partly that is because they will do
less than assembling multiple software packages.
