Hi,
I'm new to the video arena & am a bit confused about these two input/output technologies. I'm considering building a home theater w/ a projector, in looking at projectors I see that the newer ones have multiple inputs, including HDMI. Do video source units or pre/pros offer this same technology? So far (granted I haven't looked deeply), it seems like most of the newer DVD players, receivers & pre/pros offer DVI and people are using DVI to HDMI cables. Or is HDMI still an emerging technology & not as prevelant on the source side?

If you are buying into the market and can buy all your gear, TV with HDMI, go do it. It is the "next" technology that most will be using.If you have a DVI component right now, it is a better idea to stick with other DVI gear b/c a lot of people are reporting problems when a HDMI to DVI adapter is used, mainly getting the "black crush."
From video PQ point of view, HDMI has no advantage over DVI. But companies are touting HDMI b/c it is able to carry digital audio signal. However, when you think about it, the audio capability is not needed usually b/c usually people connect DVD player's video output to the monitor but don't connect the audio. The DVD player's digital audio output gets connected to the home theater receiver.
Hey Jon - thanks for the reply - it makes sense.Yes - I am an audio guy & would see no reason to connect the dvd/recorder/satellite audio to the monitor (in this case a projector that probably doesn't even offer audio). However I worry about connecting these different sources to a reciever or pre/pro - is there any concern about signal degregation? Wouldn't it be better to connect the source directly to the monitor if at all possible?
By the way, aren't HDMI connectors smaller in size than DVI? That would provide some advantage, especially if running cable through a conduit.
There's definitely the possibility that receiver may degrade the video signal and/or do odd things. I would definitely connect all the video sources to the monitor directly for video, DVI or HDMI. Then connect toslink/coax digital audio from source to receiver.There may be receivers in future that have multiple DVI/HDMI inputs and can act as "switcher" and do it well, but I haven't seen one yet. The new Panny XR70 was supposed to have that ability, but I see that it only has one HDMI input.
I have a 60" Sony GWIII(DVI only), Zenith DVB318(DVI), and DISH 811(DVI), so HDMI wouldn't be good for me.
But if you are buying gear now, then I don't see why you Shouldn't get everything with HDMI.
Great info. I'll look for sources that have HDMI when I get to that stage. But let's take a theoritical situation. Let's say I have a monitor with HDMI and several sources that offer HDMI. Now my receiver or pre/pro only has 1 HDMI input so I would not be able to have multiple sources use that receiver. My question is - are there other switches that allow multiple HDMI input & (at least) 1 output? While I don't like using switches, digital to digital shouldn't cause too much degregation (if any).
DVI or HDMI switcher is not a simple matter. For DVI switcher, several companies made/make one, but pretty much all of them had some problems or another, such as simply not working with certain brands/gear. It's not simple to get it right like a analogue switcher as it involves very high video frequency and digital circuits. And they all cost an arm.Which is why I would have automatically bought the Panny receiver or something similar IF it had good DVI/HDMI switcher. But no luck..
