I have been using clonedvd and anydvd with no problems until 2 weeks ago. Now every movie I back up only burns about 30%. I will watch the movie and 20 minutes into it, completely locks up. Now when it shows I have successfully written the dvd, I eject it and can see that only a portion of the dvd has been written to. How can I fix this? Is this caused by an upgrade, or has a setting been changed?
