Do you have pathplayer set as "Always enable" ?
Verbatim are very good quality media, what drive/burner do you have and is the firmware/driver up to date ? also what burn speed do you have set in common settings ?
Are you using the internal burn engine of DVDFab or do you have DVDFab setup to use ImgBurn ?
One more question...are you using the paid version ? because DVDFab has had support for Super 8 since v8133, if you are using the free version because their is a waiting period of up to 90 days after the support was added to the paid version.
