Okay here's how the story goes. I got 3 disks from the friend. All of which are the same brand of burned discs, containing around the same number of information, all burned within the same hour. Anyway, the first 2 disks worked perfect. Nothing wrong ever happend to them (except for one not letting me eject). Then when i put in the 3rd Disk, Realplayer wouldn't let me see it. The 3 disks also contained the same format of information: AVI. Since realplayer couldn't see it, i went to My Computer>>CD/DVD Rom Drive (D:). Then it said: "Please Insert Disk into drive D:."
I checked again. the disk was in the thing. I opened it and closed it and it still wouldn't work. I even cleaned the damned disk and it still goes by undetected by my computer. I tried a CD disk, but that worked. I tried the 3rd Disk again. Nothing happened.
