Hi - I have a Scientific Atlanta 8300HD DVR connected to a Panasonic TH-42PX60U via a HDMI cable and am not able to get any picture on the screen (it works fine on component). Is there something I need to do on the DVR to get this to work?? I have looked everywhere and can't get it to work! Any help is appreciated! I am trying to free up the component port on the Panasonic for a Wii.

Thanks
