Have seen several inquiries as to what to use to burn these files with... YES Alcohol 120% will burn these to DVD... I have just done so and the DVD is working just fine. I am using version 1.9.5 [build 3105] and all I did was go to the "Image Burning Wizard" browsed to the folder with the MDS extension file and continued with the next prompts. Hope that helps those that are stuck... btw if you ever come across a file with the extention .daa use PowerISO to burn it, mentioning it because I came across this yesterday and had to research wth it was.
