This may be old news to some of you but its the first time that I have come across it.

I have just bought a copy of 'Round about Roma' by Stefano Di Battista on Blue Note.
This disc does not seem to have been released in the US yet.

I put it into my pc to have a listen while I browsed and suddenly a player that I had never seen before appeared! Anyways the cd provides its own player but apparently will not allow me to use my usual player to rip it as I usually do for use on my ipod.

When I opened the cd through explorer it does not display the audio tracks separately.

This is infuriating (I dont share MP3s on the net and I don't download them) but I can't listen to an album that I have bought as I would wish!

I presume the introduction of the player is to get over the complaints of cds not being playable on pcs.

Any other incidents of such cds? What are other people's views?

Incidentally I tried to copy it on a 'normal hi-fi type copier and it wont copy either!

@Pio2001:

Before I forget about it: You're a HA moderator, so could you please tell me if I'm allowed to post my method to make my Plextor 121032A rip and play the copy protected disc. The way I understand forum rule # 9 I'm not, but I'm just not sure, because English is not my first language, I don't know much about U.S. laws and I saw others posting similar things without being stopped by HA staff.

To answer your question: In groups of different samples (details below) there are sometimes 2 or 3 contiguous different samples.

BTW, the CD is "Mensch" of Herbert Grönemeyer (German), EMI 2002

The first position with different samples is an exception (weird). The Plextor drive ripped about 3000 samples of digital silence (clearly audible wrong) in the middle of one song while all other drives' results are identical and sound fine at this position. IMO this is a strange behavior of the Plextor drive. C2 was deactivated, test & copy CRC are identical, I even tried with different firmware versions (with/without caching)!? blink.gif Any explanation?

Now the "regular" pattern of different samples:

1st block/group of different samples:
Left channel 459820, *845, *867, *880, *891, *893, ... last different sample 460384
Right channel 80% of different samples match left channel, same range (459820 - 460384)

Similar blocks, several 100 samples long, of different samples repeat approx. every 264600 samples.

I've got 4 wav files of every track and no matter which two of them I compare, the different samples are exactly the same (,but with different values for every drive, of course).

I'd like to know what you think about this. Tell me if you need more details about something or if my English messed up my message. The most important question for me of course is: How could I get rips with least/lowest possible errors without having to spend hours of handwork correcting sample values?
