Query: This burner is a superb piece of work!I

I bought this to replace my already ancient 1x dvd burner in my notebook. It burns in the most popular formats (-r and +r) and is very quick about it. While 8x speed media is difficult to find and expensive, plextor has rigged this wonder to burn at 8x on some 4x media. I have been successful at this with Maxwell media rated at 4x. If your on the hunt for a dvd burner that is fast and easily shared among your home network this is the way to go!
