I have a 50-inch samsung DLP Projection tv. It has a HDMI/DVI cable input on the back. And i have an HDTV DVR Time warner cable box (Oxnard, CA) w/ a DVI-D output . I'm not sure if that'll help you out. But that's the most I know. if you need to know anything else about the box. Just ask. =] But, I'm having trouble figuring out what cable to use ?
