Wheeee!.....It's a DeeVeeDee....
First, you need a DVD video capable player installed on your machine. IE: Nero "Showtime", Intervideo "WinDVD", or Cyberlink "Power DVD". There are also free players of which I'm not knowledgable. There are 3 file extensions that make up the DVD-Video format: IFO, BUP, and VOB. IFO= information: BUP= Backup(information 2) and VOB (the video itself). The easiest way to get these files to play is to take the whole group, (that constitutes the movie), and place them inside a folder marked exactly as follows: VIDEO_TS Note the Caps and the underscore. In Nero "Showtime", you would right-click the screen and follow the tree to "play from folder" then go to your "VIDEO_TS" folder and click-it. You can also nest the "VIDEO_TS folder inside another folder with the title of the movie your trying to play, but here again you must all capital letters.
