My experience with burning video (several thousand) is that most errors occur on the outer edge of the disk. If you can reduce the file size a bit you may eliminate your problem.
www.afterdawn.com is another site that talks to dvd burning and media.
Moser-Bauer is considered mid grade media and should work fine for data. TDK is made by several manufacturers ranging from very good to lousy, I won't use it because you can't tell which you are getting from the packaging. There are several utilities out there that can pull the media ID code to tell you which company actually manufactured the dvd. If reducing the size doesn't work or isn't possible, I'd try a high end brand to prove it isn't media. I've had very good success with Taiyo Yuden, Mitsubishi (Verbatim), and Ritek (4x) media.
