I'm looking to get a set of cables for various connection conversions. If I buy a cable such as this one for example, will that get me both an RGB compatible and an YPbPr compatible cable in one? No-one on eBay, Amazon, etc seems to make a distinction but I thought they worked very differently.
On a related note, is it worth buying cables like this from eBay or Amazon? A lot have gold plating, double layers of shielding and so forth, but they are still very cheap.
