I've tried using Nero Info Tool and Dvdecryptor to get the information on the manufacturer of my dvd media, but they both keep showing that the manufacturer is unknown everytime I put a bland dvd in. However, after I use the same dvd to burn a movie and use the two programs again, they would state that my media was manufactured by Richoh and so on. Is there a way that I can use dvddecryptor or Nero Info Tool to see which manufacture the media is from before having to burn it to find that information out? Thanks.
