Dear listers, perhaps some of you can help. I bought a Redhat7.1 distribution with a local magazine. However, one of the CD's is of a different color than the second one. I can successfully install the first CD, however, the reading of a second CD fails after a minute or two of copying. Once my friend told me that the color of the CD can confused laser. Is that true? What can I do about that? I tried the second (problematic) CD on both of my CDROMs and the same behavior takes place. I already changed the copy of the magazine for a new copy, but this did not help. I'd appreciate any advice. Vic
