Thank you for CPRM support.![Wink](https://forum.dvdfab.cn/core/images/smilies/wink.png)
But Passkey doesn't work to rip cprm DVD-VR discs with Liteon DVD Drive LH-20A1P.![Frown](https://forum.dvdfab.cn/core/images/smilies/frown.png)
By the way,cprmgetkey021.exe and cprmgetkey022.exe can get title key,media key,disc ID,and etc. with Liteon LH-20A1P,but other types of cprmgetkey.exe (i.e. cprmgetkey038.key) can't get these information with this drive.
So I always put all types of cprmgetkey.exe in the same folder.
