Anyone got an idea how to decrypt Japanese DVD video recorder files using an iMac OSX? Lots of advice, but all the recommended apps seem to be Windows based.
Looking for a solution specifically for the Apple side of things...

Anyways here are the steps I used. (Still valid and working in 2021!!)
Step 1 - Use windows XP (windows 7 doesnt work), parallels virtual machine is ok
Step 2 - Copy the relCPRM_00664 folder to the c:\ (drive)
Step 3 - Check the DVD is viewable in windows explorer, if not install Nero InCD (note, Nero InCD is needed otherwise an error will occur when trying to decrypt the vro file)
Step 4 - Launch relCPRM.exe
Step 5 - Although in Japanese click on the [BROWSE] button to the right of the first text field - this is the SOURCE location
Step 6 - Navigate to the *.VRO file. In this case /DVD_RTAV/VR_MOVIE.VRO
Step 7 - Although in Japanese click on the [BROWSE] button to the right of the second text field - this is the DESTINATION location
Step 8 - Leave all the setting as default - do not change!
I didnít tick the settings in the picture a previous user posted and it worked (but maybe slower,
feels like it is doing nothing, but just wait).
Step 9 - Click the [START] Button
Step 10 - On completion of the decryption and copy you will be presented with a "Process completed" pop-up window
just click [OK] to continue.
Extra note. Regarding the DVD drive, I was using an external SuperDrive. I assigned it to Mac OS to insert and read the disk, then assigned it to the windows XP virtual machine to decrypt.
You will need an intel based Mac as the newer M1 chipsets canít run intel based windows operating systems.
