I just can’t get my head around this problem that occured some time ago. All of a sudden I can’t read DVD’s from my external DVD-drive faster than about 12x. It used to work flawlessly, but suddenly this problem was there. I’ve tried with several DVD-burners, problem is the same. What could cause this? The drive is connected via USB2, and I had no problems before. This is very annoying to say the least. Thank you for any advice.
