Hey Guys, New member here but a veteran to the sport. I used the search feature and didn't find anything. I am encountering dark burn rings on the writable side of a completed DVD-R back-up movie. I have never encountered this in the past and I have experience with 8 different burners, over a dozen different burning programs and countless brands of media. The dark burn ring appears about 50% between the hole of the disc and the outer ring. It's about 1/8th of an inch thick and is slightly darker than the other written area. I am using a brand new Sony DRX-840U (about 10 DVD-R burns only) and Sony brand DVD-R media. When I watched the movie, about 20 minutes in, it froze for about 20 seconds and then jumped to the beginning of the next chapter. Any ideas? Thanks in advance for your inputs.
