Had a strange occurance while Charter tried to install my new DVR. Connected with the highest speed Monster HDMI cable it refused to accept. Was prompted by TV (I believe and not the receiver) to use component cables to receive access. Newer brand DVR, (like last 2 weeks so I was told). It accepted signal using a cheep Charter provided HDMI. Trouble shot the Monster cable and it checked fine. Any similair situations or suggestions.
