I live in Argentina (South America) and yesterday was the first time that I buy a copy protected cd.
I just wanted to post some things that happened to me when I tried to rip my EMI copy protected CD Live Licks from the Rolling Stones.
I have two drives, cd recorder ASUS CRW-5224A and a dvd recorder ASUS DRW-0804P.

I use EAC to rip my cds so when I inserted the cd in my cd recorder, EAC could not rip it, the ripping process stop at second 40 of the first track and the red light of the 'error correction' window started without stoping and the extraction speed went to 0,4, so I decided to stop the process.
When I use my dvd recorder, EAC did not have any problems ripping the cd and everything went just fine, it was like the cd wasn't copy protected.
I use 'secure mode' with Drive has 'Accurate Stream' feature checked, 'Drive caches audio data' checked and 'C2 error' unchecked'


Reading some posts here, I read one where a guy used CDex to rip their cd. So I did it with my cd recorder and my surprise was that CDex did not have any problems riping the protected cd.

Then I read another post where a guy used ISO Buster to extract the audio in wav mode, so I did it with my cd recorder and again, the ripping process was just fine.


The questions are:

Why could I ripped the cd with my dvd recorder and why not with my cd recorder?
I didn't have any clicks or anything like that, why is that ?
Why people hear clicks on the ripped tracks?
Is there any way to avoid these clicks?



EDIT: About playing the cd in my cd recorder drive using foobar2000, I could do it with AnyDVD on with the option 'Remove CD Digital Audio Protection' activated.

Was CDex configured to extract in one of it's secure modes?

Yep, in Paranoia, Full mode with lame_enc.dll 3.90.3 --alt-preset standard.

Maybe your DVD recorder have better error correction algorithms. Or maybe there was an error that triggered an unstable behaviour from the CD recorder by chance.



It depends on the version of the protection and the drive used.



To use a standalone CD player, or to emulate the error concealment of a standalone player in software.

What DVD recorder was it? Apparantly, many drives are designed to circumvent Copy Controlled Audio Discs. LiteOn drives are particularly renound for this trait (both my LiteOn drives can rip without "glitches" EMI Copy Controlled Discs).

On a side note... EMI even copy controls their $7.95 CDs. I bought one the other day just cause that CD had an acoustic version of a track that I love.

All I can say it was a waste of money on EMI's part, it got ripped by EAC rather easily using a LG DVD Burner as the ripping drive. I can't remember the model number but it was the first dual-layer burners released by LG. Read offset was +667

my 52327s cannot rip The Tea Party's Seven Circles in secure mode. I have to do it burst.

The LG GSA-4120B can rip Cactus-protected CDs easily. I tested it with 2 and it ripped them in secure mode at >10x. It burns very well too. It's so good it can even write on toilet paper.

My CD-Drive (Creative 5223 or something like that) rips
Apocalyptica's copy-controlled "Reflections Revised" aswell. No clicks, no problems.
Surprising.

Well guys I can tell you that it's not so easy as it seems... I have many rips of copy protected CD's but although they all are click/pop-less (by listening flawless) they never match the CRC of test & copy. I'm not sure but I think that the secure mode is no longer as secure as it is with normal (non copy protected) CD...

What are your secure mode settings ?

As for secure mode: Accurate Stream & caching checked, C2 unchecked, Automatic read command, read offset correction +6, overreads unchecked, allow speed reduction, Gap detection A - secure, write offset -6, UPC & CD-Text write checked.
This is for my TEAC CD-W552E and for my DVD reader TEAC DV-516E the same except the offset correction +594.
Test & Copy are used with burst mode, of course!
PS: I have a weird experience - I have Megadeth's remasters 2004 they are CDS200 and 2 of 4 I grabbed with no problem by secure mode but the other 2 never match CRC and secure mode is unusable...

I have similar experiences with CDS200 discs as well. However AFAIK, there are several versions of CDS200 being used. Previously, I had managed to rip such discs with EAC's burst mode (secure mode takes painfully long) and consistently get CRC OK (can't remember the versions). However, with a recent disc also protected with CDS200 (version.txt on the disc says CDS200.5.0.150/5.00.160), I am unable to get CRC to match. I believe this has something to do with the various versions of CDS200.

Yeah, you're right but do you expect the CD's from one serie (Megadeth Remix/masters) to to have a different type of CDS?
I've tried two of them I have now by my hand and it's:

"Peace Sells... but Who's Buying?" (1986 Re-Issued in 2004)
CDS200.5.11.90
5.10.090

- pretty weird... Why there are two different version's written?

"Youthanasia" (1994 Re-Issued in 2004)
CDS200.5.11.90
5.10.090

- so the same thing!

I did notice that you mentioned the discs were from the same series. While I do not expect different CDS200 versions to be used, there's a possibility that different versions might have been used as some form of test, perhaps to see which is more effective? Well, just a hunch anyway .

By any chance, are these two discs you checked for the version either the two that you managed to get CRC OK with or the two that you were unable to match CRCs?
I'm not exactly sure why there are two sets of numbers, but based on past version.txt files the numbers above might be the version number and the numbers at the bottom might be some sort of build number.

Both of them have about 5 songs CRC match and the rest (15-17 tracks total) does not match... The other 2 of the remasters which were ripped in secure mode I don't have at home right now...

The other explanation is that both my drives are draw near the end of their functionality, I hope it's not the case...

Other interesting thing is, that on my TEAC CD-W552E the function "detect TOC manually" don't work (neverending scanning of the CD) and the CRC's never match by burst mode on copy protected CD's... Also no timing problem showed which is very strange because on my DVD reader when audiable error occurs it's mostly in the place where timing problem is reported by EAC...

I'm still helpless although I'm searching already half a year on various webs for help...

Er... help about what ? Don't expect to rip CDS200 CDs flawlessly, the information was erased, destroyed, and lost before the CD is made ! You can't recover it. It never got into the glass master to begin with !

Yes Pio2001, I know it... but as you've written in another thread and beyond, you can rip copy protected CD's with matching CRC's and that's a certain indicator for me...

I'm probably doing something wrong or don't understand something because for me it's a huge difference between the CDS CD ripped with matching CRC's and with random results..., you know what I mean?

Sorry, maybe I'm something missing, so please clear it up for me!

On the Doc Gyneco single, I couldn't get matching CRC at all either, whatever drive or speed I used. It must be the CD's fault.
