UPDATE Today I contacted the Maxell representative and talk about the problem I got with the spindle I bought recently. This person asked me to go his office for an exchange. He gave me a new set and I do test the media with three different softwares (1Click DVD Copy, Solid Avi to DVD Burner and Nero). Tests were positive. The only I noticed is that these discs now read 8X and also read DVD+R Video. The others read 16X (although I tried to burn at 4X.) Thanks for the comments and advices I read here in this forum.
