I am new to this so please bear with me. I have a Motorola Dual Tuner DVR Cable Box. I just got a Samusung HT-HDP40 Reciever/DVD player go with my Samsung 32" LCD. I chose the HDP40 because it has an HDMI in and out. The motorola has a DVI jack, so I connected a DVI-HDMI cord into the HDP40 HDMI in and then connected an HDMI cable from the out to the in on the LCD. While I can watch DVDs, the cable signal won't come through the reciever and into the LCD. I know its not the cords themselves because the HDMI cable works for watching DVDs and I tested the DVI-HDMI by plugging it directly from the cable box to the LCD. The LCD continues to work fine with just using component video cables, but I would like to try to get it to work using the HDMI cords. Any thoughts would be appreciated. Would the fact that the cable box uses DVI and the reciever uses only HDMI make a difference? I was told comcast has a new HDMI box. Thanks.
