I just received 13 DVDs in trade, and they came on Dyson blank media which is coded as Prodisc F01 DVD-Rs. Out of the 13, only 4 play on my DVD player, or on my PCs. I put all of these problem discs in my JVC DR-M10 DVD recorder at home and got "Unreadable Disc" for each. Then I put them in all 4 of my DVD drives at home and the computers acted as if the discs were blank. The DVD drive in my Dell PC at work also can't read it. Even DVD Decryptor says "Disc is empty". Yet there is clearly something written on the discs. DVDInfoPro says the disc is blank, and says the disc is "not a DVD-Video".
Below are the DVDInfoPro comments on this mess. (Bad disc followed by good disc).
Any idea what is going on?
