Hi Gristy,
The last time I burned to DL, I first ripped whole disc to a folder using Fab decrypter. I did not burn to ISO. I then used Fab platinum to burn full disc sending to dvd9 with the Img Burn engine instead of VSO. Flawless!! The only thing is Img Burn will stop and ask you to pick the layer break. It lists the best chapters to do this on and you pick one and go!. Not quite sure why it doesn't just pick for you but it worked great.
