Dvd download time to hd

I have experience with “{dvd shrink, colone dvd. xcopy plus, and any dvd” downloading a move to hard drive approx time 30 to 40 mins. However when my computer freezes or nero freezes on 2x -r disc the next time i go to use any of these programs the download times doubles it seems, i have reinstalled the prog. etc if i repair windows all is well again. Is ther a window file causing this?. any workaround for it, thanks.

maybe DMA mode has been deactivated
