Some clown sent me some dvdrs in trade which appear "empty" in both my burners and in a Panny dvd recorder, but my Pioneer player can play them. I'm thinking they might be unfinalized, as they were made with a recorder (or maybe vcr-to-computer). He might be using a duplicator to pass along dvdrs he got from someone else. I don't want to copy them from Dvd Player to Recorder. Is there some program that will magically allow my computer to see the discs? Isobuster and Testdisk don't see anything in the burners, either.
