CPRM problem

[kner]

I was able to rip and playback CPRM discs with Liteon LH-20A1S and LH-20A1P by using the previous virsion 7.0.5.7.

But the newest virsion 8.0.0.2 couldn't do so "only" with Liteon LH-20A1S and LH-20A1P.

( I was able to rip and playback CPRM discs with BD-ROM ASUS BC-1205PT,MATSHITA BD-MLT SW-5583,Optiarc DVD RW AD-7173A.)

For the sake of reference:
cprmgetkey021.exe and cprmgetkey022.exe can rip CPRM discs with Liteon LH-20A1S,but cprmgetkey041.exe can't.

A new virsion cprmgetkey.exe cannot alway handle with more DVD Drives than old virsions cprmgetkey.exe.
So I always have all virsions of cprmgetkey.exe to rip CPRM discs.

With regard to cprmgetkey,the following Japanese web site ( in Japanese)
has various information.

Hi kner,

Please try Passkey 8.0.0.3 to see the result:



Thanks.

The latest virsion Passkey 8.0.0.3 beta was able to rip and playback with BD-ROM ASUS BC-1205PT,MATSHITA BD-MLT SW-5583,Optiarc DVD RW AD-7173.

But Passkey 8.0.0.3 beta couldn't do so with Liteon LH-20A1S and LH-20A1P.

Passkey should be able to rip and playback with Liteon LH-20A1S and LH-20A1P,because the previous virsion 7.0.5.5 beta was able to rip and playback with these.

Passkey 7.0.5.5 can decrypt CPRM on LITEON LH-20A1P and LITEON LH-A1S.But it can't yet on Optiarc DVD RW AD-7173A,MATSHITA BD-MLT SW-5583.

cprmgetkey.exe + lernel.dll + cprm2free.exe(or c2dec.exe) can decrypt.

I upload a passkey logfile.
In this logfile,drive letters imply the following.

G: Liteon LH-20A1S
H: Optiarc DVD RW AD-7173A
I: BD-ROM ASUS BC-1205PT
J: MATSHITA BD-MLT SW-5583

Hi kner,

Please re-download 8003 and try again to see the result.

Also, please post new passkey_internal.log, thanks.

I re-downloaded and re-installed the new Passkey8003(MD5:f7a005d512f7768b46ed584d9dac0526).

The new Passkey8003 can decrypt CPRM with Liteon LH-20A1P on another PC,but can't with Liteon LH-20A1S.

Since the old Passkey8003(MD5:4f0404bd7328e5d3f215ce7e871bbcd8) can't do so with Liteon LH-20A1P,the new Passkey8003 is improved.

Needless to say,the new Passkey8003 work well with BD-ROM ASUS BC-1205PT,MATSHITA BD-MLT SW-5583,Optiarc DVD RW AD-7173A.

Passkey8004 couldn't decrypt CPRM with Liteon LH-20A1S.

Maybe Passkey works well with all DVD/BD drives except LH-20A1S,so I couldn't care less.

Sorry!

The CPRM protected disc which I inserted to Liteon LH-20A1S or my LH-20A1S might have a problem.

After I inserted another CPRM DVD-RW disc to LH-20A1S,I was able to playback it by using Passkey8.0.0.4.

Passkey has no problem with respect to CPRM.
