Does anybody know where the macrovision flag is contained in the VIDEO_TS.IFO (or other) file? Most of the DVD backup programs remove macrovision and therefore are editing this file.
Also, IFOEdit has a "remove APS" function (APS is analog protection system, aka Macrovision), but I cannot find what it's changing in the .IFO file. I've specifically taken unaltered .IFO files from known macrovision-protected DVDs and used this IFOEdit choice on the file, and the resulting file seems to be identical to the original, i.e. no changes are made.
So, what alterations are DVD Shrink, DVD Decrypter and others making to get rid of it?
