I've tried to burn a couple of iso's to disk but when it gets to around 30% it comes up that there a data error: cyclic redundancy check. I've tried on two different iso's at first i though it was corrupt but now on the second one as well I'm not sure. I've burnt to disc's before using the same disc and program. I tried using Nero and ImgBurn. And I've used Verbatim and sony dvd-r and no difference some help please?
