I have a Samsung SD-616E DVD ROM drive. Just bought it a month ago. Works fine with all CD's and Digit DVD's. Now the problem comes when I try to run DVD's burnt by DVD Writers, like I have this DVD of a concert given to me by my frnd who can access it on his DVD ROM, but I cannot. I only notice this problem when I am trying to access "burnt" DVD's and NOT "pressed" DVD's. Are there any drivers or applications that need to be installed to read these DVD's ? I checked on the Samsung website and they do not offer any drivers. just instruction manuals.
