Vista - HDMI from HD set top box to Media Center - possible?

I'm not aware of a card that has an HDMI input that will allow you to bring the signal in to your Media Center computer, but there are graphics cards that have HDMI outputs so you can connect from your computer to the TV. Here is an example:

Hi ktriebol,

Thanks for the link.

So i can get the picture out to the TV via HDMI .... i just need to find a card that will accept HDMI in from a set top box?

Does it have to be a TV card or will a graphics card do?

Sorry if this sounds like a noob question .....

Like I said, I am not aware of a card for your computer that will accept input via HDMI. As far as I know, there is no such animal.

You should also be aware that if you choose to use a grahpics card to output video and sound from your computer to the TV via HDMI, your motherboard must have an SPDIF output for sound. You will need to connect a cable from the SPDIF output on your motherboard to your graphics card so that the HDMI connection will have sound as well as video. Most current motherboards have an SPDIF output on them but older motherboards do not. If you buy a graphics card with an HDMI output, it will come with a cable for connecting the SPDIF on the motherboard to the graphics card.

do you think this will do the trick?

thanks for the tip on SPDIF

That sure looks like it would give you an HDMI input (actually two of them) on your computer. I noticed that there was no definite information regarding whether or not this card supports HDCP. This is very important. All of the video-handling devices from the source to the monitor should support HDCP. If they don't support HDCP you will have all kinds of problems with successful handling of video. If you want to learn more about HDCP, you could start with this link at wikipedia.

The good news is that almost all new computer video components support HDCP, so my guess is that this card supports HDCP also, but I would want to be sure of that before I bought it.
