I'm pretty sure this is not on here, but here i go. Ever since i got my dvd burner dual layer 8x16x8 i'm satisfied, fast to me. I was backing up my dvd's in Dvd Shrink to my hd in about 9-13 min's. And burning them with Dvd Decrypter was flawless. I was happy it was great really quick. Ever since i downloaded the trial version of Nero to enable burning with dvd shrink this is when it all slowed down, and locked at all 2x speed for read, write, burning ect. It takes 2 hours to complete the whole thing which before it took like 15 mins to complete the whole process. Btw the trial is over on nero, and i decided to unistall nero today. I also read about enable DMA instead of the PIO which is all enabled still no difference. My comp. is running great and efficent i'm pretty sure its nero trial which basically f'ed everything up. My computer is a dell P4 2.8 Ghz, 80 gibabyte hd and basically this is the only thing thats bothering me. If all could help i would greatly appreciate it .
