I cant seem to get my Sony DRU-710a to burn at 8x for the life of me. Its a brand new unit I installed just tonight... any suggestions? I have already tried the DMA/PIO switch, I have gone from Memorex 8x DVD-rs to TDK 8x DVD-r's... any other suggestions? As it is now its taking me about 45 minutes to burn a full DVD-r, and NERO says that is at 8x on a TDK dvd-r. I know that at 4x on any cheap media I can burn a full dvd-r in that amount of time... I guess I am assuming that an 8x burning would cut that time in atleast 1/2?!?!?
