Okay, I am not sure what the source of my problem is, but here goes... I am currently backing up a DBZ disk on my computer. I have had no problems with any of the other disks of the series, but for some reason every time I stick this DVD in the computer, my computer does not even recognize it as being there. My drive E, which usually is labled DVD/CD Recorder, changes its subtext to CD only. When opened, nothing is there. The Shrink does not recognize it either, nor does any of my burners/players. What is happening? 1. is this a form of copy protection 2. am I missing a codec (i just recently reinstalled my OS) Any suggestions???
