I'm having a similiar problem with an NEC 6500A. It cannot read a DVD-R. For some reason it appears that the DVD-R is blank when it has stuff written on it. I've tried it on other computers and it works fine. I'm going to start pasting in random stuff, because I don't know what will help. The computer notices that a disk has been inserted, but it asks me what to do with a blank disc. Again, I know the disc is not blank because it works on other computers. I'm sorry if I'm posting in the wrong spot or am clearly stupid, but I'm at my wits end.
Thanks
