So, if I'm reading this right, it sounds like you downloaded the torrent files, and want to know how to play them. Is this correct?
If so, then greencpt is correct - these are the standard DVD files, and you need only burn them as such onto a DVD (assuming you have a burner.)
If you don't, then save them to a directory (a separate directory for each movie, since many - if not all - of the filenames will be duplicates, and after starting up your software DVD player, select "Play files from hard drive" (or something along those lines.)
If you wish to make it an XVID (which really isn't necessary at this point, since these files should fit on a DVD anyways), there are many programs that will take the existing DVD structure and recompress it (Dr. DIVX comes to mind.).
And please don't be afraid to ask questions in the future.
