WinData DVD+R DL doesn't seem as bad as I thought after all ...

I had some hardtime burning my first dual layer DVD using WinDATA DL disc. But then when I tried again, one on my desktop and one on the USB DVD burner, it seeems like it's not that bad. In fact I think I will burn DL on my external DVD Burner from now on since that one support buring at much lower 2.6x speed and the verification was success on both the external burner and my internal burner.
