I recently bought the following kit Pioneer VSX-AX5iS AV receiver DV-668AV DVD player PDP-434HDE PLasma screen Sky+ It's all connected up and is running fine. What I would like to know is this. Q: At present the DVD is connected to the tuner via conponents and the sounds goes to the reciever via digital coaxial. Could I not use just a HDMI connection and have less cables and better quality picture and also use a optical toslink instead? The sky+ is using scart plus a toslink. Also what is the iLink connections used for. Is that batter than HDMI and optical? Last but not least HDTV? Is the Plasma I bought HDTV ready????? A bewildered beginner!
