I have made a complete backup copy 1 of 1 to iso of Avatar Fire & Ash, Hoopers, & Bridesmaid’s & when I try to burn to a 50gig BD-R DL the software won’t finish the procedure 100%. It will write to the blank disc, but the outcome will be only 5 minutes of the movie & then it will go straight to the end on the copy disc. Also, on the time to complete in dvdfab timer it will decrease as usual until it gets hung up around either 15% or sometimes 33% & then the timer will start to increase upwards & after 5 to 8 minutes it will give the message complete, but the outcome will only be partial of the movie compress instead of the full complete movie. Any help will be appreciated? I am using the Full disc in copy mode
