A friend of mine ran a 35' DVI cable from his equipment rack to his HD DLP projector when he had his house built a year or two ago. He has since upgraded to a new projector with an HDMI input and is looking at getting a new DVD player with an HDMI output. Given that the common link between the two is already in the walls, he will have to use a DVI to HDMI converter and an HDMI to DVI converter on the other side to get digital video to work. My question is, since both devices are now native HDMI, will the projector be able to receive control commands over HDMI (one nice feature HDMI offers over DVI besides also carrying audio)? Or will the conversion to and from DVI remove this feature? And just out of curiosity, would a connection setup like the one above still be able to pass audio over HDMI?
