I'm shopping for new HT equipment and one criteria I had for the DVD player was that it have DVI output (like the upcoming Denon). Assuming my digital cable box also has DVI out, are there devices out there with multiple DVI inputs? The RPTVs I've looked at seem to have only one DVI input. Are there brands or models that have more? Are there high-end recivers that offer video switching for DVI? How do you deal with multiple DVI inputs?
