I have an external dvd burner that is giving me lots of problems when I'm trying to burn dvds. It is plugged into its own outlet so it is recieving adequate power, it's plugged into the main usb port, and it is set up correctly (as far as I know). It's a 16x burn but it wont ever burn a perfect dvd at speeds any faster than 1x when it decides that it wants to. I've wasted 2/3 of the blank dvds that I've bought so ANY suggestions or help would be greatly appreciated. I searched and couldn't find any updates for anything, but I also ran the nero cd-dvd speed tool and found that it ran along a normal path but it had large spikes in it about every 1/10 of the cycle. I'm not sure what I can do to correct that, if anything.
