I found that ImTOO DVD Ripper is a powerful DVD backup tool, which can help you convert or extract your DVD to other popular video and audio formats, such as MPEG, AVI, WMV and MP3, etc. So I post this guide here, wish it could help you
1. Run
DVD Ripper and load your DVD into the program. It can be done easily by "DVD" button on the main interface or the corresponding option in the "File" menu. At this time, your DVD disc should have been put into the drive.
And then, in the following dialog-box, please just select the DVD drive of your PC. And then click "OK" to get your DVD loaded.
2. Or you can load your DVD by "Add IFO Files" in the "File" menu. IFO file is the information file of the DVD. You need browse your DVD disc to see the files. They are in the "Video_TS" folder of the DVD. But generally we do not recommend this way because some DVDs would not be able to be loaded properly by reading IFO files.
3. After your DVD is loaded into the program, you will read the titles/chapters of your DVD in the central list of the program. There are always certain titles on a standard DVD, while each title consists of certain chapters. You can control whether chapters can be seen in the list or not by pressing the button between "Title" and the red one.
4. Generally, the main episodes of the movie would be made in one title. As the program shows for the DVD, Title_01 has 28 chapters and its duration is 01:25:34. It is one of the longest titles of the DVD. So the main episodes of the movie are in this title.
If you just want to rip it entirely, please highlight this title in the program and set other output options. Or if you only want to get certain chapters ripped, you still need highlight them in the program first. You can check whether what you highlighted is what you want or not by previewing it in the program.
5. On the top of the list, there are settings for "Audio", "Subtitles", "Angle", and so on. All the audio tracks and subtitles that your DVD has will be shown in the corresponding box. Please select what you want for the final output files from the lists. You do not always need change "Angle" options. Angle 1 will work well for most of DVDs.
6. And then, please select the output formats and other necessary things at the bottom of the list. What you select in the "Profile", what output format you will get after conversion. If you want to keep what you ripped as one single file, the default setting for "Split" will be OK. Or you can select other "Split" options. The default option for "Zoom" is "LetterBox", which will give black borders to the top and bottom of the final output files to fit aspect. You can select other items to meet your special need in the list. In the "Destination" folder, you should tell the program where, or which directory on your hard drive, will be the output path for the conversion. You can "Browse" the directory or enter it directly.
7. On the right panel of the main interface, there are some advanced setting options, such as "Video/Audio Codec", "Video Size" and "Video/Audio Bit Rate". Generally, the default values we offered haven been OK, so you need not always modify them.
8. After you set everything OK, please start ripping by running "Rip Selected" in the "File" menu. It will get what you highlighted in the program ripped only. If you just simply click the red button on the interface, all the tick-selected items, chapters or titles in the list, will be ripped.
9. After the conversion is done, you can reach the destination folder and find output files by "Open" button on the main interface directly. What to do next? Just enjoy the movie on your PC by proper media players.
