When I add all video files to Nero Express and start to burn them, error message appears showing "DVD-Video files reallocation failed. The resulting DVD-Video might be unplayable. Do you want to continur?". I then quit the process and start with Nero Buring Rom again but with same warning message. Please advise what has gone wrong and how I can solve this problem to enable burning of those video files into DVD. Many thanks for the assistance provided!
