I was just wondering: which types of cables have variable quality (depending on price & manufacturer), and which cables are all the same? In other words, what type of cables can you buy cheap and they'll work perfectly, and what type do you need to make sure you have quality ones? I'm building a HC, so I'm talking about video cables here, such as composite, SCART, S-Video, component, RGB, DVI and HDMI. Is it simply just the digital ones (DVI and HDMI) that are consistent? By the way, what's the difference between component and RGB? Does component include a black and a grey channel (brilliance and saturation?), like the cable at the back of my monitor has? What is that cable at the back of my monitor? Bonus question: is digital really noticably better than a good analogue connection? I saw a Monster SCART connection in Comet today and it was really clear I can't imagine anything looking much better than that.
