Unfortunately I do not have a PS3, do you happen to know if there are any other ways to check for it?
Oh I wasn't saying it wasn't, and I appreciate the advice, I was just wondering if there are any other ways to tell if a disc has it, since I don't have a PS3, and really don't want to get one just to check for that protection.
Hmm, so I don't know if there are any other ways to check for that protection, unless AnyDVD were to tell you if it detects that particular protection in the status window for the disc, though I'm unsure if it would. But here's another question. If one chose not to check the box when the disc was ripped to the hard drive, would one be able to go back and create an ISO from the folders, or use the original ISO of the DVD, (if one chose that route.) would they be able to remove the CSS Mastering Errors from the copy without the original disc?
You're (possibly) reading too much into this thus over complicating things. I think CSS Mastering Error is an actual "mastering error", and not a copy protection mechanism. So... if a particular DVD wont play in a DVD player when it normally would, try making a copy with box checked and see if the copy plays. Personally I've never, ever encountered a DVD that I purchased that didn't play in a DVD player.
Back in the day, I used the term 'mastering errors' to cover discs where the key changed in the middle of the file at some point. So it would be decrypting fine one minute and then output garbage the next. Enabling that option made it attempt to find the key at vob/cell id changes rather than just at the start of the file. Maybe it's still something like that ?
If the option to detect mastering errors is enabled and it detects it changing... yeah maybe. Only it's authors would know for sure - or someone with such a problem disc. I must have one in my collection somewhere.
Yes, but I believe it checks for a new key only at the layer change. This was enough for all the broken CSS discs I've met (very few).
