So, i just got a NEC 2510A burner, and a Samsung DVD-Rom. For the first like 15 copy's it took about 10-15 minutes to read the DVD , then like 10-15 more to copy it. For some reason now, the same discs take about 50 mins to read, and then 10-15 to copy. Any thoughts on why all of a sudden the read time would greatly increase? Or just anyway to speed up the read time.
