I found title 27-1 is much better than 31-1.
Here's my setting using 6.1.2.5:
Read: Under Reading Error Control,
= set to "Ignore all reading errors authomatically"
Write: Burning Enginee = set to "ImgBurn"
PathPlayer: = Disable
Once the above are set, restart the DVDFab and insert the disc.
Since my computer is too slow, it took 10 to 15 minutes to read scanning media,
I even got a message of "vertual memory are low", I just ignore this message.
Select Main Movie, select the title 27-1. You have to make it sure the preview
(lower left corner) indicates the title 27 Chapter 1, then cleck 'NEXT' to burn.
I used rewritable disc for testing and it works just fine.
Hope it will work for you too.
