I bought DigitalMax 16X DVD burner and installed NeroExpress. Today was the first time I tried to use it. I tried to burn a DVD+RW. The total size of the files was about 660MB. When I started the burning, the remaining time shown in the NeroExpress was about 3-4 minutes. However, when this time was up, only several percentages were done, and the program continued burning. The burning process did not finish until one hour later. It means that the burning of 660MB took about one hour. I noticed that the buffer level of the recorder shown in the NeroExpress during the burning is only 6%. Does anyone know it? Thanks a lot.
