its really easy, to figure out actually. This is all you have to do. go download winrar, from http://www.winrar.com open up any of the rar files, you only need to open one of them. Select extract, and put in the directory you wish to extract them too. Once you have done that winrar will extract the image file to where you told it too. The whole file will now be extracted. Once, this is complete go to Nero, select burn image, and select the images you would like, and you are done.
