I read somewhere on this site that there is some free software out there that tells you the manufacturer of disks you put in the drive. I think its called "disk identifier" or something like that but i can't find it on line. Any suggestions appreciated.
Just click on the Blue link in last post.It does cd's and dvd's. Or You can also get this program to check the manufacturer code: http://dvdinfopro.com
If you're burning movies, you should already be using DVD Decrypter, since its free and the best utility out there, and it will show the media id of the disk in ISO write mode.
