I have just started using imgburn and am having issues right away. I am trying to take a blu ray disc to an iso on my hard drive. Everything appears to work fine, no errors etc. Ive tried just iso, ive tried iso, udf etc. They complete and are 43g which is good. when i try to mount it, and watch it, it fails. this same process worked fine with the trial version of anydvdhd, but thats lapsed now. any help would be much appreciated. thank you
