Well, in fact it's the first version that was available in France and the quality is not the best but still pretty good. It was manufactured by Philips. Some years later Pioneer made a remastered edition of this LD. I heard the Pioneer looks amazing compared to the Philips first release.

Plus, the cover of the Pioneer remastered edition is damn beautiful! I'll try to get my hands on one of these copies as soon as possible.

I don't know if that has something to do with how the colors look, but i recently bought this LD and it was in mint condition, the seller told me that he played the disc only once.
