Could you clarify this statement? I couldn’t understand what you are saying here. However, I can confirm that I received the same “false positive” that cdripper did. According to AnyDVD 220.127.116.11 and 18.104.22.168 (which now has AI, similar to your pathplayer technology), and also DVD Decrypter 22.214.171.124, there are only “invalid VOBUs” present. DVD Decrypter alone cleaned this up nicely when making a .ISO/.MDS image. Does DVDFab lump “invalid VOBUs” into the “structure protection” category? I thought that was reserved just for ARCOSS, Ripguard, etc… Meanwhile the other utilities seem to keep this simple protection in a separate category. However, even if you are lumping the “invalid VOBUs” into the structure protection category, the bad sector report DOES seem to be a false positive. DVD Decrypter would have otherwise choked on a true bad sector without a “protected sector list” file for it to work with.
Recommend you separate invalid VOBUs in the report, since the user can choose to just use DVD Decrypter to make a nice image file if that’s all it has. It continues to handle this simple protection without issue.
