Ok I finally decided to get digital cable from Comcast. I had been using analog cable without any problems. Here is the equipment I'm having trouble connecting: Denon 3805 Infocus X1 Comcast Motorola DCT6412 Dual tuner HD / DVR I have my projector working fine with analog cable and watching DVDs though my Humax DVD/DVR. The Humax is connected to Video 1 and Optical 1 on the back of the Denon and is using the DVD input on the selector dial, this works like a champ. I connected the comcast box to Video 2 which is the second set of component in connections on the back of the Denon. I also connected to the second set of optical connections for audio from the Comcast box. I go into the Denon config and tell the TV input to use the video 2 (component) inputs. I also tell the TV input to use digital connection 2 for sound. I get sound but no piture. I am using a component to 15 pin cable to connect to my X1. If I take the reciever out of the loop and connect to the X1 via composite video it gets a picture. So I know I am getting the picture from Comcast. Thanks in advance for any help Ron I just took the reciever out of the loop and connected the component to 15 pin cable directly from the cable box to the projector and still no picture.
