They do not just make DVD\'s gold, "just because", the dual layered discs are the only ones that have gold on the bottom. It is used because the laser and see though the layer and read the layer that is under it.
Also, from what I am hearing it isn\'t some "gold" problem, well, it kind of is. It sounds like most of these problems are happening when there is a layer change, which only happens on gold discs because they are the only ones with layers, duh. There are many players that have problems with layer changes. This is just something that we have to put up with. DVD technology is going though a kind of puberty. We just have to wait for it to develop.
I have this problem with Fight Club, however I found a way around it. I just have to turn the diagnostic mode on before I player it each time (if you need help on diagnostic mode it is on page 9). A pain in the ass, but if it lets me watch Fight Club, I\'ll be happy. Sony just better fix this in the DVD update.
