I just upgraded my original DirecTV receiver to an HD DVR. Unfortunately the new outputs are a little different. I'm running to a Marantz projector. Originally, I was doing this through a RGB cable connection, but the new DVR has no RGB output. It does have the HDMI output, however. Is there an adapter to connect the HDMI/DVI cable to my RGB cable? If so, is this a good idea, or should I just set up a component connection with three cables. Or is there another route you suggest? I hesitate to buy a HDMI/DVI cable to connect directly to the projector as it would have to be a pretty long cable and I already have the existing RGB cable. I'm new at this and unsure what connection will give me the best picture, esp in HD. Thanks so much for any help and advice!
