You did not state what program you ripped it with or in what format. If you ripped it as a ISO then you would have to use dvdshink or another program to convert it to dvd format. If you backed it up as dvd format on the hardrive you should have a folder video_ts that has the files for the dvd and one shoul be a video_ts.ifo file which is the first video play file. You can right click on it and open it with windows media player. nero player, powerdvd player or one of many others out there and it should then use that program to play the video. here is a site that explains the dvd video_ts folder files better than I can
There are many players program out there that you can use besides windows media player some are free and others like powerdvd which I like and use cost money.
Hope this helps
