I have just bought a Panny TH42PV500. I watch only Sky digital and DVD. What connections should I use to optimise picture quality for both these sources. I am a total novice and have not got a clue so not too much techno jargon please. Do I need to buy extras to optimise these. If so what are they? Also, buying a new DVD player ..... which one will go best with the Panny .... dont mind cost ... want quality.
