Hi 1st post. I have purchased this system last week and so far not happy. Is there anyone with this system that can talk me though some settings & tips? The reviews i read were good and i am really unhappy at present. I have a Sony KDFE42A10 tele with 1 HDMI port and a SKY HD box. My setup at the moment is optical from sky into DAV-DZ830W, the rear speakers sound is really poor so far. I decided to plug the rear speakers in last night rather then use the wiresless function and the wires only reached about 1.5meters which i find a bit strange. I am thinking of sending these back. HELP!
