One Tree Hill Season 3 Disc 5 won't copy



Has anyone else had problems with this disc in this set? I am using the latest version of DVDFAB Platinum and also tried with the previous version, yet I cannot get through more than around 50% on copying the 5th disc in the One Tree Hill Season 3 set. All the others in the set went fine and burned without problems. I’ve used PP both on and off for this disc, and once let it run over 12 hours 'til it just stopped. On every try it copys fine, then just slows to a crawl, unti it stops copying completely at 50% on the VTS_03 file. I have not had any problems with any other discs, they have all copied and burned fine. I would like to finish up this set and this one disc is just not cooperating.
