Changing a video_ts (vob file) to a video mpeg

I used DVD Shrink to backup a copy of a movie the other day, and went to my hard drive where the file was. I clicked on a video_ts file (vob file) and noticed that when that file played, it was the beggining of the movie that has sound, then says “HBO Special Feature”. I would like to add this file to the beginning of some home movies as a joke, using Ulead Video Studio 8. But the file cannot be used I guess with it, because when I try to add that clip, it says that it is a file missmatch, and can’t be used. Is there a way that I can somehow convert this file to a video, mpeg file , so that I can use it with VS8?
