ImgBurn is known to be one of the best, probably THE best burning programs for dual layer burns. It will set the layer break correctly on dvd video when others, like Nero, fail.
Here is one way to do this. Break encryption with AnyDVD. Do not use the built-in ripper, use DVDDecrypter in ISO Read mode or use ImgBurn in Read mode to make the ISO and put it on the hard drive.
If you used DVDDecrypter, load the mds file into ImgBurn since it holds the layer break information. Burn to Verbatim +R DL media, burning at 4x speed. Or use the ISO if you made it using ImgBurn. (Edit: ImgBurn also makes an mds file that you can use)
This process works. Do not use any other DL media other than Verbatim, preferably Verbatim made in Singapore.
