How do I watch my .vob .bup and .ifo files all together?

I popped a dvd in my disk drive and opened a folder to view its contents. I took all of the content's in the dvd's folder which is called VIDEO_TS and copied them to my computer in this folder I have nine files. There are two .bup files and three .ifo and the other four are .vob's. I sort of figured out the vob files but not really and used media player clasic and it won't play all the vob's just a few and the ones it will play are like the begining of a movie then it goes to what would be the menu in a regular dvd. In other words I can get the menu to start but I can't press play the file is done playing and the menu screen is on and when i click play nothing happens. Also I used video lan and had the same results I know there is prob some expensive program out there or something that will do it but all i can mess with is freeware so please help me I want to watch my step father in law on this video so bad!!!!
