At first I thought it was a bad/dirty disc. Not the case. I have tried multiple drives (2 internal, 1 external) and even borrowed a friends DVD to try it. Using the CloneDVD option it stops scanning disc at 74% (VTS_25_1.VOB) and in the CopyDVD Titles option it stops scanning at 25% (VTS_34_1.VOB). This failure happens with both discs on the afore mentioned options at the same places. I am attaching the latest logfile to this post.
