Well you are using the correct dual layer blanks However are you bitsetting the discs before burning , a lot of players have trouble reading dual layer discs if not bitsett
Have not used fab but I do use shrink and dvd region free (have not yet encountered a disc I could not backup yet) Shrink will remove the layer break when ripped in file mode , I then use discjuggler to burn which auto bitsetts the disc and they will play on all my friends drives perfectly . at this stage region free works on all au movies good work fengtao
