Hi Brendon and d-deweywright thank you both for the quick response. Ok, I think you both have provided me an answer to my tormented brain cells. Yes, quote "they are not playable on a standard CD player nor in a computer." The cover sticker mentioned that 'Plays Only On SACD Players'. But I saw on youtube that this guy demonstrated on how he was able to extract SACD ISO file to dsf www.youtube.com/watch?v=2QfhDOylzE4. My only issue is that how did he get those 4 files on to his computer? Wrote to him but he never responded. I thought Roxio was capable of doing this trick (LOL). Obviously, it wasn't meant to be that straight forward. Nevermind, at least I have tried.
