Hi all i have a Sony DRU-810A that supports just about every dvd format, but last nite i was trying to write a dual layer disc and Nero said it cant write to ML-R discs, even though the packaging of the Verbatim disc says Dual Layer. Any idea why this might be? Also, does anyone know were i can get dual layer disc's from or recommend some maufactures that make good quality DVD Dual Layer Discs? Thanx.
