Well, first of all, you either right-click one of the files and go to "Extract file..." and choose where to put the resulting file or you double-click on one file to open it up in WinRAR and then click on "Extract to..." at the top.
Once you've done that, you SHOULD get one of a number of things:
1.) One large ISO file (with perhaps a .cue file or something).
2.) An MDF file (with a corresponding .mds file).
3.) Some other disc image file.
4.) A bunch of seemingly random files, which are the contents of the disc.
Anyway, all you have to do then is burn the disc to DVD using ImgBurn or Nero or whatever you like. Just make sure you use good media and, if you're burning onto DVD+R, that the Booktype is set to DVD-ROM.
I'm pretty confused right now. Am I changing the Booktype to match the manufacturer of the disc or the drive that burns the disc? Because if it's the disc, I'm using Imation. If it's the drive, I'm using LightScribe.
As far as I can tell, you change the Booktype setting of the DVD burner so that it burns the DVD as a DVD-ROM. So yes, you'd change it depending on the DVD drive you're using.
