It starts out at 2.4x speed and then it slows down. I saw it drop as low as 1.7x but it was on 1.9x most of the time. It took about 26 minutes. I don't know why it burns slower than 2.4x with nero but slower is probably better than faster for these old discs. Oh and btw, thanks for making such a great burning app! I use it for everything except making audio cds from mp3s.
