Dont know if anyone can answer this but here goes. I have connected my hx510 to my hitach 42pd7200 via component on av4 I have my scart from my sky going in on line 3 via rgb If I wish to watch dvd on component, I have to disable the rgb out in the menu. Fine. However, does this mean that I am not recording the RGB IN signal from the sky box? Am I now only getting a composite in? And therefore recording composite only? When I have the component out st, The system menu lets me select Decoder for line three as opposed the previous setting of RGB/Video... Jesus, I am confused..... Any help or infor would be most happily received.
