Rip DVD in Windows 7

DVD contains folder and file which are specially developed for DVD player but not for computer. If you import a DVD on your computer, you will see Video _ TS and Audio _ TS. The Audio _ TS is empty. And the extensions of Video _ TS files usually are .VOB, .IFO and .BUP.
The .VOB files are actually the .MPEG or video files and only these files contain video. The .IFO files contain information like scenes and time. The .BUP files are backup files of the .IFO files. These files aren’t related to computers. If you double click a .VOB file in the occasion of not having any DVD player installed on your computer, the computer shows that it can’t open the file. But there is a method that will let your computer play this file.
