Hi I'm a complete beginner and have just purchased a 42PWD7E and sony dvd home theatre system. I currently have sky+ connected to the tv with S-video. the DVD and speakers are connected to the sky+ with scart. I presume I need to connect the dvd system to the Tv otherwise i cannot play dvd's through to the tv. What connect should I use? I have a component board TY-42TM6Y board with av/component/RGB connections in the TV. I also have not changed nay settings on the TV - do I need to adjust anything to improve the picture? Thanks for your patience with a beginner!
