Strange Stuff here.
When Burning DVD-R with both Pioneer 106 and 107, the end of the movie is freezing.
Latest version of Nero downloaded, latest firmware of the DVD-writer flashed. Always the same shit. Worse: Nero gave a succesful message even when asking to check the 'Written data' after the burn.
Finally I updated the Bios of the MB Asus A7N8X-X from 1005 to 1007, and now everything works fine..
