I've recently shared the same interest. So just posting some game capture information that I have been doing. Thought I would fish for some opinions.
Testing captures of a DOS / Win9x system. Started mainly with interest towards a 3dfx Voodoo2 for video and an Aureal SQ2500 for digital 2CH audio.
In a dedicated PC, my capture card is a StarTech PEXHDCAP60L. I was getting some analog noise when capturing with VGA from the Voodoo2. I used very heavy shielded cable too. I was also concerned the same may be true about the analog audio. So I came up with this idea to adapt it all to HDMI. It produces a very clean image. Find a VGA to HDMI converter, that does no scaling. It also makes for a very coinvient way to deliver audio if you mix it onto the same cable.
3dfx Voodoo2 (VGA) -> HDMI adapter -> StarTech PEXHDCAP60L DVI adapted HDMI input (with audio!).

I really liked both of these. The Hammerhead is "better" in the sense that it supports a lot more VGA input resolutions, such as those found in POST and DOS. However it only has analog audio input. So the MNXO is another I tested, which supports optical audio input. Works great, but it does not support as many obscure VGA input resolutions. Both are very handy.

So the point being, instead of capturing directly from VGA output, to a VGA input, what are your opinions on this approach? I can find no noticeable lag. I even introduced a 2 port HDMI splitter. One going to my HDTV or Gaming monitor while I play, and the other to the capture device.

Do you think this approach messes with any color formats? The adapters do absolutely no scaling. I can send 1024x768 exactly to an HDTV (that understands the resolution) and a capture device with HDMI in. It does not show up as 720p or 1080p on either. I have not tried multi channel audio, but the adapter is supposed to support it. I just don't know if you can capture it.

Any reason to think the PEXHDCAP60L is not as good as or equivilent to a Micomsoft SC-512N1-L/DVI ?
