After RB Pro was completely finished, I got a statement that said, "Difficulty in Creating ISO. No ISO created." I was having it created in a destination file on my hard drive. It did create a VIDEO_TS file. I used Img Burn (Build Option) and burned the ISO, but I would like the ISO on my hard drive. I have checked the settings and they say ISO. DVD Decrypter is set to ISO also. Any ideas?
