In order to convert DVD to PSP video, you need to download DVD to PSP Suite first, it includes two individual products, a great DVD ripper and a powerful PSP Video Converter, and install them one by one.
Launch DVD Ripper and load DVD. Please choose "Open DVD" in the File menu or directly press the "DVD" button in the main interface, then select your DVD-ROM in the pop-up window and press the "OK" button. After you successfully load the DVD, the DVD info is displayed in the left window.
You can rip entire movie or just one or several chapters, or copy any segment of the movie from "Setting" menu; If you want to save as specific file size, please set the "volume size" combo-box in the Output area.
Click on the "Format" dropdown list in the Output area to select an output format such as AVI, MPEG, etc. If you want to specify the output format setup, just click "Output Settings..." in the Settings menu to set. You may select the Output folder by clicking "Browse..." or directly enter a path in the "Output Folder" box in the Output area.
With all settings being properly done, click the "Encode " button in the main interface or choose "Encode checked Item(s)" in the File menu to start ripping. In general, the default when you load a DVD is that all titles/chapters are checked.
After an successful ripping, close the DVD Ripper and Launch PSP Video Converter, load the file(s) ripped by the DVD Ripper by clicking the "Add" button in the main interface or choose "Add" in the File menu.
Highlight the loaded file and choose output format from "Profile" combo-box. Here, you must select "PSP Video Format (.mp4)" for your PSP. Click "Browse..." button to select folder or entering the path directly to decide where to save the output file; "C:\temp" is the default one.
Click "Encode" to start converting. After the conversion is done, there will be two output files for each single loaded file. One is the .MP4 video file, playable with QuickTime on PC, another is a .THM file. Both of them are necessary for PSP. The two files are in the same main title, for example, if your original file is "test.avi", after the conversion, you will get two files: "test.mp4" and "test.thm".
Connect your PSP with PC, and copy those two files into "H:\MP_ROOT\100MNV01" (where "H" is the drive letter of your PSP). Rename your files in PSP. You must rename them to "M4Vxxxxx.MP4". "M" and "V" should be capital. There would be five random numbers followed "M4V". The numbers must be same for the two files. This is quite important, or your file can not be played on PSP.
What to do next? Just enjoy movies and videos on your PSP!
