With purchase of any 123studio software. Check it out at their website, www.dvdxcopy.com . I am not associated with this company in anyway, I have one of their old products, and am happy with it. If the spec is accurate, this is an unbeleivable deal. Most of the 4x dual format DVD writers out there (Sony, Pioneer, NEC..) cost anywhere from 60% to 100% more and none come with an 8MB internal buffer. I just brought a DVD writer from a fellow HTF member (hasn't even arrive yet), else I would have looked into it seriously.
