A SURPRISE Update:

Batman: The Dark Knight Rises has been FOUND!! YAY!!

Now that I've announced that I want to say something about my discoveries .... when I get these I usually get dupes of cinema discs I'm looking for so they won't have all the normal info on the face of the disc. I do have some actual discs that are not dupes .... but not many. These dupes work NO different than the originals. A DTS machine would recognize them as they would the original disc. Other finds I have are straight 1:1 ISO's of the discs I am looking for so I have to burn them or use them straight on the PC.

Hopefully this clears up why I may not always have answers to certain questions like dvdmike's. There are however ways to find out as borisanddoris has shown.

Cheers!!!!
