I have Die Hard 4 on my PC HDD. It's 2 folders, (BDMV) & (BDSVM) I converted both folders to an ISO using ImgBurn. When it was finished I had an ISO that is 38.1gb and something that says MDS which is 9kb. I took the ISO only and burned it to a blu ray using Nero 8. It would not play in my PS3 nor my PC. What have I done wrong? If I use Power DVD it also will not open the ISO but will play if I move both folders to it. It shows though only the making and then claims improper file and plays more of the making. What am I doing wrong and how do I get this to work?
