I read this a while ago at www.hometheaterhifi.com (a great source for technical info) and found this in the article "DVI and HDMI Connections and HDCP Explained":
"DVI is an 8 bit RGB signal, while HDMI can be 8 bit RGB, or 8 bit, 10 bit, or 12 bit YCbCr. If you have a DVI source and DVI display, there will be no problem. If you have a DVI source and an HDMI display, again, no problem. If however, you have an HDMI source and a DVI display, the below-black video information may be lost in the translation. There is a bug in the Silicon Image HDMI transmitter that pops up when converting YCbCr to RGB." This was written November 2004, SI may have resolved this by now.
Currently source material (DVD and HD) is 8-bit color. Not sure if we'll ever get beyond that or if we really need to. But I felt it was necessary to show there is a difference between DVI and HDMI and that it wasn't just the audio capability HDMI adds.
