with clone dvd, in the burn process, it goes through several steps. first,it creates dvd files. then it gives you an option to either burn to dvd disc, or create iso imag... i use create to iso image, to save for a later burn.---now, i just upgraded to a new windows 8 machine. on my old vista machine, creating an iso image for a 4.36 gb dvd, it would take around 2 minutes. on the new windows 8 machine, it takes around 15-20 minutes. any suggestions of what settings i need to change, or is it in my operating system?
