ImgBurn 2.4.1.0 on Windows XP Professional SP2 failed to 'Write files/folders to disc'.
The disk gets burned and the DVD plays for 55 mins and then fails. I can see an odd looking ring near the outer edge of the DVD.
I can use ImgBurn to create an ISO and then burn it to a DVD. The resultant disk works just fine with no odd looking rings at the outer edge.
