I had a sony dvd-rw 4x, i only had it a few months and for some reason the write speed doubled to around 30 mins instead of around 15 mins, i use nero 6 ultra edition. I tried using different burning programmes, still the same, i tried different dvd-r media, still the same. So after getting pretty p1$$ed off i just bought a pioneer 8x dvd-rw, but the write speed is still double the time that it's supposed to be. Ok i'm burning discs at around 15 mins but there has to be a reason why the write speed is double the time it's supposed to be. So if anyone has any ideas or answers. PLEASE PLEASE PLEASE let me know. Thanks.
