CloneDVD Too Long?

[JPunisher]

I think its the drive. I have 2 drives and my speed varies depending on which one I use to read. It takes me about 25 minutes on my pioneer dvd rom 12x and maybe about 35 minutes if I use my plextor writer 12x dvd+r which should read about 16x. I know for sure that its not the ram or hard disk as I have changed both and notice no difference. It's strange because my old dvd rom drive has better times than the new dvd rw which is supposed to be faster. I think it is the smart burn feature, which varies the speed of the drive to create a better burn, is the cause of this.
