Hi Peter, The disc is from the same pack, so that shouldn't be the problem - but I will try a new disc from a new pack in case the disc was faulty. I get the feeling that this error code is generated by windows rather than p2e, and is almost certainly linked to the dvd burner software. I did have problems with the disc formatting last time - maybe I should insert the disc in the drive when p2e prompts me rather than putting it in the dvd burner at the start? Deekay
