Summary: I purchased a new system from a local authorized Denon store who is a reputable audio/video dealer. They came and unpacked the boxes and set up my system including an Aquos 42" LCD HD TV, the Denon 2307CI, etc. to mate with my new HDDVR from DirecTV. The set up included use of HDMI cables for all video and audio between the new components. After set up everything seemed to be working fine until the first time I turned it on when the technician wasn't present.
