I am getting this verification error whenever i enable Verification since the Dvdfab version where the disc verification speed was increased(i don't remember the exact version):
21:30:27: Burn DVD folder (D:\Hancock\FullDisc\HANCOCK) started
21:55:39: Burn DVD completed successfully
21:56:03: Verify DVD started
21:56:04: Task_3 failed! Error=100
Otherwise the dvd burning is quite fine.
