Just to clarify the original errors were reported by DVD Decrypter, not ImgBurn....DVD Fab managed to backup successfully
Thanks all....
Yes and No.
Yes, it seems there is a new form of copy protection on that and other recent Sony DVDs. See this story : New Sony DVDs Not Working In Some Players
No, that has nothing to do with the problem you saw with ImgBurn - which is simply that ImgBurn will not by design read any copy-protected DVDs.
