Can anyone tell me what the DVI jack and cable is for on a high definition plasma tv? Is it better than component or s-video? What source outputs in DVI.?

The DVI connector is used to connect it to a HDTV tuner, and yes, it is a lot better than s-video. Computers also use DVI ports, but on my Sony, it says not to use it with a computer.

There are DVD players out there that output on DVD. Technology wise it should give you a better picture than component but it comes down to your plasma and dvd player. Try it and see. It might blow you away and it might not.

Depends whether or not you have a fixed pixel display or not.

I have a Samsung DLP TV. DVI is hands down the best input on it. It is very picky, though. Not all TV's have the same resolution.

The best part is that you can use much cheaper computer cables just fine with a HDTV set with DVI.

DVI is also being used with HDTV Set Top Boxes too. There are a few a DVD players with DVI output as well.

RGB VGA input (analog PC monitor type, HD15) is the next step down. Better than component. A $25 triple shielded PC monitor cable does the trick.

dvi should technically be the best, as it's the only output that is truly digital (no analog conversion). my tv has dvi input and i'm hoping to get an htpc running via it soon.

Yes DVI in most cases should be better. Imagine running a long digital cable is better than 3 long analog cables (component). It still depends on the DAC and quality of cable. If the digital-analog conversion in the set sucks, it's possible it may make no difference or be worst.

Thanks for the responses. My DVD player does indeed have a DVI out, also (which I never noticed).

But, if I hook the DVI cable up, instead of the 3 component video cables, will I lose the progressive scan?

You won't lose the progressive scan. Something to watch out for though is what resolution the DVI output supports. Some DVD players only do 480P. There's some which upsample the signal to be HDTV compatible like 720P, 1080i, etc. Ideally you'd want it to match your display otherwise it will be reencoding it again.

Oh yeah, DVI may be digital, but it's not very tolerant of long cable runs. One the major drawbacks.
