Took delivery of my 37 inch PV500 today and have connected it to sky via scart and sound through pioneer amp (VSX2014), using simple phone leads. Have connected a pionneer 575 dvd player using component to plasma and coaxial for sound to amp. The problem is one of lip-sync when playing any DVD. Hear the dialogue seconds after its said. Is this a cable problem or do I need a new DVD player, perhaps with HDMI and i-link to go with the amp? Any suggestions please????
