Well, I got this unexplained error: somebody I know wrote me something on a few CD-RWs using (the latest, I think) Nero with a Plextor and we don't know why we got this error... There is no error report when burning, but when trying to read from the CD-RWs it's only possible till something like 45%, then I got a strange "Invalid MS-DOS function" error... I tried to play a movie beyond that point and it worked... It seems to be just some error in the middle, always on CD-RW, but never on simple CDs. Could that Plextor malfunction?
