I have had DTV come the last 2 days and install their new HD DVR but I cannot get the HDMI to show a picture. All I get is "not supported mode" on my Samsung LCD 46" TV. My other HD Receiver (non DVR) worked just fine with the same cable. I have tried Components and they work fine. I also have tried HDMI mode and component mode on my TV and only component mode worked. DTV says they will send a third one and to keep using components for now. I don't want to use the components, that's why I bought the HDMI cable! I also have a surround sound cable hooked up to the receiver but I don't know if that makes a difference. Can anybody shed some light on my problem?
