Still need some basic help here. Question: Which of the following is likely to provide the best picture for my Philips 30" lcd? RGB scart (from Sky box) to RGB scart input, RGB scart (from Sky box) to VGA input, RGB scart (from Sky box) to Y Pb Pr input. This subject has been discussed in part in lots of places but I'm finding it really difficult to track down a straight forward answer. Thanks a million.
