Although some of the disks that I have work, I keep getting a message that says that the titles have failed. Sometimes it completes several title son a disk but fails only those with the main program in the content. It happens "randomly" across multiple disks and 2 different OS.

Only guesses can be made without logs. See the FAQ in my signature for how to turn on debug logging, and copy/paste the portion of the log that shows the errors in a message here.

Here is a log of a try that I redid to get a log. It copied all the others titles on the DVD fine, except for the main movie itself.

Sorry... Should have read all the way through the link above. Support ticket has been entered.
