DVI to HDMI 'adapter' problems

[jamie marchant]

I am trying to hook my macs up to my video capture card using a DVI to HDMI adaptor. The capture card says it's out of range even when it's displaying at resolutions I know it can handle. Any thoughts on this?

So it would seem that DVI normally uses the RGB colour space.  HDMI can either use YCbCr or RGB but my capture card can only handle 'YCbCr'. Unless there is a way to make it use 'YCbCr'(which I don't think there is), it looks like I won't be capturing off of my Macs that way.
