I'm a member of other forums and someone sent this to me and I thought that I would share it with you. It doesn't work with Kingdom Hearts yet, but does work with FFX-2 and might work with FFX. I did this myself and it can take up to a couple hours. If you have any questions feel free to contact me any way you want. Hope you enjoy.

How to rip PS2 FMV/PSS files.

PS2 game FMVs are encoded on the disc as PSS files. Some programs can easily find them but for games like Final Fantasy X and X-2, they are hidden. This guide should help you rip footage that is hidden.

Programs you need:
DVD Decrypter
PSS Plex
The file splitter
Nova software extractor
MF Audio (Removed the MF Audio link)
DVD2AVI
Virtualdub (Divx/Xvid encoding)
Tmpegenc (MPEG encoding)


Step 1: Ripping the PS2 Disc
Put in your PS2 disc into your DVD-ROM/DVD Burner then run DVD Decrypter. Go to "Mode", then "ISO" and choose "Read". Then rip it to your hard drive by choosing "file" > "Decrypt". You should now have a large PS2 game ISO on your hard drive.

Step 2: Splitting the ISO
Open up The File Splitter and under "File to split", choose your PS2 game ISO. Select the folder on your hard drive you want the split files to be for "Folder for pieces". Then under "Size of Pieces", choose "Custom size". Make the custom size 1 GB and then choose "split" to split up the ISO.

Step 3: Extracting the PSS files
Now start up Nova software extractor and under "Files to scan", pres the "Select" button next to it and choose the split ISO files (They should end in a number). Under "Save extracted files to", press the "Select" button next to it to select the directory you want to store the extracted files in. Then under "Formats", choose "MPG". Press "Start" to begin scanning the split ISOs. The scanning process may take a while but it will show you the movies that you can extract from the game. Once the scanning process is done, select each of the mpg files, click on "properties" and change the mpg extension to pss. When you are finished, press "extract" to extract the pss files to your hard drive.

Step 4: Coverting the PSS files to MPEG2
Open up PSS Plex, choose "Demultiplex", then under "Select PSS source file", open up any of your newly made PSS files. Choose the directories you want the save the MPEG2 stream under and then click "start" to save it. Ignore the wav file it creates here because it will be distorted. Your MPEG2 stream should be saved as an m2v file.

Optional step: Getting the sound
Now that you have the footage, you can also get the sound if you want to watch the movie file on your computer. However, if you just want the movie file, then skip over to Step 5.

Start up MFAudio and click "open" and choose the pss file you want to extract the sound from. You can press "play" to see if it's the one you want. Click "save as" to set the directory you want the wav file saved to then click "process to save the wav.

Step 5: Converting the MPEG2 stream to avi
Open up DVD2AVI and select the m2v file then choose "save avi" and choose the codec you want to save it under (huffy preffered" then press ok.

Now you should have a large, yet fully working PS2 avi for video use.

If you want to attach the audio back to the movie, you can use virtualdub. Open the avi in virtualdub, then under "audio" select "wav audio" and the wav you extracted earlier then the audio should be back with the movie. If you want to encode it into mpeg with Tmpegenc, you can load the m2v file for the video stream and the wav for the audio stream. You can encode the movie into whatever you want from this point or use it for a video.

ONLY WORKS FOR 2000-XP

I got this from the same forum. It only works for Final Fantasy X-2. Enjoy, and if any questions arise contact me any way you like.

FFX-2 FMV Extraction Guide For Windows 2000-XP
############################################

Needed programs
ISOBuster
Universal FFX2 Tool
PSS_demux.zip
DVD2AVI
Virtualdub (Divx/Xvid encoding)
Tmpegenc (MPEG encoding)
-------------------------------
Insert DVD to your drive, open ISOBuster and select the drive FFX-2 is in. Right click "Session 1" found on the left column in ISOBuster. Select "Extract Session 1 <image>" and choose "User Data(*.tao, *.iso)" and save this file as ffx2img.iso
-------------------------------
Once done, open up Universal FFX2 Tool. Click the search button and locate the image file you just saved. Set the "path to stored extracted files" to a directory on your hard drive that EXISTS. Now press "ExtractLBA + Check DVD". Wait till its done. Can take a while depending on speed of your computer. When its done, DO NOT CLOSE the program yet. After thats done, press the "Extract Files" button in the Universal FFX Tool program.
-------------------------------
After its all extracted, close the program and go to the directory with the extracted files.
Theres lots of files in here, all with no extentsion. Sort these files by size. Now the only files we are interested in are files greater than 10mb. (there should be about 22 files)
Move these files into a different folder. Or you can delete all the files besides the ones > 10mb. Now sort these files by name. You should see files with small numbers eg FILE17, FILE19 etc and files with large numbers eg FILE9366, FILE9367. Its the files with large numbers that we want. There should be 11 of them. As the file numbers may vary between different extracts and or NTSC/PAL disks, I cant give you a solid number for the file names. But if you have FILE9366 like I did, the last file would be FILE9376.
Add extentsion .pss to these 11 files.
-------------------------------
Open PSS Demux and drag and drop each file into this program, one at a time. You will now have 11 *.m2v files, 11 *.wav files and 11 *.dat files.
We only need the m2v and dat files.
The dat files are actually ac3 encoded sound files. If you have the ac3 codec, you can rename these to wav files and open them.

All thats left is to convert the m2v file into your movie format of choice and add the sound to it.
-------------------------------
Step 5: Converting the MPEG2 stream to avi or mpeg
Open up DVD2AVI and select the m2v file then choose "save avi" and choose the codec you want to save it under (huffy preffered" then press ok.

Now you should have a large, yet fully working PS2 avi for video use.

If you want to attach the audio back to the movie, you can use virtualdub. Open the avi in virtualdub, then under "audio" select "wav audio" and the wav you extracted earlier then the audio should be back with the movie. If you want to encode it into mpeg with Tmpegenc, you can load the m2v file for the video stream and the wav for the audio stream. You can encode the movie into whatever you want from this point or use it for a video.
