Um no.....those colours are simply from the plastic layers on the disc reflecting the light and acting like a prism. You can see it on audio CD's and CD-roms as well, not just DVDs.

Okay, this is kind of complicated, but I'll try to explain it. Back in the 40s and 50s, the world was in black-and-white. People at the time didn't realize it (because it was all they knew). Then in the 60s, things started getting color. It was kind of a grainy reddish at first, but then it started getting sharper. But the digitally recorded images of the earlier times didn't get colored in the transition, so we still observe them in black and white. The DVD, though, is a product from today, so it has rainbow colors even though the digitally recorded image from before is in black and white. Make sense?

for the complete solution about why the light reflects in rainbow-colors at all i would recommend reading feynman's quantumnelectrodynamics.
Cause light does not travel a straight path. light travels every possible path and the surface of such a DVD interacts as a filter keeping specific wavelengths of light from wipening themselfs out.
For getting a better answer on this you may return this DVD to the shop and claim that the pattern is not black and white, and you want your money back cause of that.
would be interesting to see their faces there.
THAT kind of pattern IS black and white then :-D

No it wont. Its not that the color of the disc tells you what is inside. The disc has data stored in form or arrays of concentric circles. Like you had records in old days. Its just the total internal reflestion that makes it look like rainbow. nowdays the disc come in different coatings (blue, silver) to protect DVD dissc from scratches. But one thing is sure from the disc you can tell approximately whther the disc has been written in full or half or partially as it shows.

Not at all. The colors you see on the back of the disc have no relation at all to the content of the disc, just the material the disc is made of.

No, but an imaginative question.
