HI all, I have been ripping DVD's for some time now and used the same media (Datawrite Yellow Ritek G04 4x) I have around 120 that have been sucsessfull, now I have bought a new batch and around 3 out of 10 have worked??? Anyone have any suggestions? I have not changed any software, but I did have a Virus which seems to have gone now. Is it wise to Format and start again? I can't waste anymore discs! Any help will be gratefully recieved! Thanks Alan.
