I posted a while back about the HDMI-DVI cable from Pacific Cables that didn't work with a bunch of components, the 975V being one of them. In this brave new world of digital connectors, any number of things can go wrong. Don't count the player out yet. I hate to say it, because it costs too much to buy on speculation, but if you can get hold of a Monster HDMI-DVI cable, give it a try, rather than the separate adaptor. Maybe there's a high-end video store not too far from you that will allow you to try one, or something equivalent, at home. If you honor the protocol of eventually buying from them, they'll often let you try a cable out. As I said, I had trouble with my first cable; I bit the bullet and bought the Monster. I suppose you could buy a cable from one of the manufacturers on the web as well, and just send it back if it doesn't work. There are a bunch of good ones. I won't bother to give a litany of names, but if you need a few suggestions, send me a PM.
