Click the "Add" Button and browse your computer, find the DVD folder of the movie you want to add from your hard disc or DVD-ROM, open your DVD folder, select the VIDEO_TS folder and click OK.

Click "Format" drop-down button to choose the output format;

Click "output" to set a location for output file;
Once everything has been done, you are ready to start conversion. Move your mouse to "Start" button, click and the conversion is on process.
Once loading your DVD to the converter, there are many chapters including the menu. Check or uncheck some chapters to copy.

It could be a boring job when more than 10 titles are there for you to set the output format and location. To save time and effort, click "apply to all" button
to apply settings to all chapters. Then a confirm box pops up like this.
Click yes to continue. All title settings change, see the picture.

If you have a close look, you will discover some more intimate settings. See the picture.
Now, stop worrying about wasting power or folders confusing. This DVD Ripper tool will turn off your computer or open the output folder after the DVD backup is complete.
