kopiosuojattujen levyjen rippaus....

Onko Bomfunk MC's:n Burnin' Sneakers -levystä useampia eri versioista / painoksia? Kaveri oli ostanut eilen levyn Citymarketista ja oli sitä kokeillut heti MP3:ksi vetäistä. Ja ei, ei sitten millään.
Noh, tulipa kaveri minun luo ja kokeiltiin oikein porukalla. Ja ei, ei sitten millään. Hassua tässä on, että toisen kaveri samainen levy (joka on aikaisemmin) ostettu toimi hienosti ja se saatiin MP3:ksi.

Eli onko levyn julkaisija (Sony?) päivittänyt kopiosuojaustaan vai onko tässä uudessa levyssä joku uusi mekanismi varmuuskopion estämiseksi? Ja niin juu, levy muuten ei toiminut Kenwoodin auto-boxissakaan, että mikähän on?

Miten porukka on tästä levystä kopion ottanut / MP3:ksi vetänyt? Tussilla suttaamalla uloimman raidan? Vai toimiiko joku ohjelma, jos, niin mikä?

 

Eli eli, seuraava on copy paste CDFreaks:n forumeilta. Linkki alkuperäiseen threadiin on http://club.cdfreaks.com/showthread...b39a7e3220&threadid=46159&highlight=key2audio tuossa.

Key2Audio (Example: Shakira - Laundry service)

A Key2Audio protected audio cd can be recognized by visual inspection as follows:



Warning stating 'will not play on pc/mac' on the front/back cover and labelside of cd.

Textstring 'Sony Music' or 'Sony dadc' on the innerring on the data-side of the cd.

How to copy/rip a protected audio cd:

General considerations:

Audio protections are hardware dependant protections, based on your reader. This means that when you have the 'right' reader, audio protections will give (almost) no trouble copying/ripping. But it could also mean that when you have the 'wrong' reader you won't be able to copy/rip the cd at all... The writing part is not interesting because all available writers are able to write protected audio cds.

Tricks used by audio protections: illegal Table Of Content entries, multi-session tricks. A normal audio cd-player is a single-session device, it just reads the first session where the audio tracks are, it isn't bothered by the extra sessions because it can't read the extra sessions. Also, an audio cd-player expects only audio-tracks so can't be confused by illegal TOC entries which claim that the audio-tracks are data-tracks. A Cdrom-player (or dvd-player, cd-writer) is a multi-session device, it tries to read all sessions. But these (illegal) extra sessions are purposely added to the cd to fool the cdrom-player. Also, a cdrom-player can read audio as well as data, so it can be confused by illegal TOC entries which claim that audio-tracks are data-tracks.

Because the protection is hardware dependant we can classify 3 categories:



reader is (almost) not affected by protection and just reads the cd. Plextor (all models) is a wellknown example of this.

reader is affected by protection, but is still able to read the cd using tricks.

reader is affected by protection and can't even read the cd using tricks.


1.) You are lucky, you can copy/rip the protected cd relatively easy with programs like CloneCD, Feurio or ExactAudioCopy. You might need to tweak the advanced settings of these programs.
2.) You are still able to copy/rip the protected cd with the marker-trick.
3.) You are not able to read the protected cd, whatever you try, you won't succeed. Only option: try another firmware which might make your reader able to read the protected cds.

General tips regarding the used software:

CloneCD v4 is the easiest way to backup your audio protected cd. Just use the audio-profile which reads only the first session so your backup is not protected anymore.
Feurio can be used to rip the tracks. Of course your backup, when writing the ripped tracks, isn't protected anymore. Feurio is able to detect illegal TOC entries and gives you the option to ignore the further sessions and illegal entries. If you succeed in reading the protected audio cd with CloneCD you should also be able to rip it with Feurio. You might need to tweak the advanced settings of Feurio first.
Exact Audio Copy can be used to rip the tracks. Of course the protection is gone after ripping. In some cases you might need the option 'manually detect TOC' in order to be able to rip the tracks. The advantage of EAC is its secure reading method (which has nothing to do with the protection).

[update 2002-05-20]
Always try to let your application to close the cd-tray with the protected audio cd in it. Do not insert the protected audio cd earlier because Windows might interfere with it and 'activate' the protection. Programs like CloneCD lock the drive so Windows can't mess up things. Again: don't insert the disk to early!
[/update]
[update 2002-05-25]
In order to prevent Windows (or the firmware of your drive) to access the protected cd too early, you also need to make sure that you have disabled 'auto insert notification' and 'auto play'. These options can be disabled through the device manager or the registry, depending on your Windows version. CloneCD also has a special entry in its settings for disabling these settings.

How to copy/rip a protected audio cd if the above mentioned methods don't work:



make a digital copy using your audio cd-player and a soundcard.

make an analog copy using your audio cd-player and a soundcard.


If your audio cd-player has a digital-out and your soundcard has a digital-in, you could connect the two and use the 'record audio data'-option from Feurio. Total Recorder is also able to record from line-in.
If your audio cd-player has no digital-out or your soundcard has no digital-in, you could still connect the 2 the analog way. Just connect the line-out cinch-plug with the line-in minijack-plug of your soundcard. Again use Feurio or Total Recorder to record incoming audio data. The disadvantage of this method is you are copying in the analog domain, your digital data is converted twice which might degrade the resulting copy. In practice an analog copy can be very good, but we CDFreakers prefer the best, so we go for the digital copy!

Että tuommoista. Taitaa oma polttava HP olla polvillaan tuon kanssa. Aika jännä että CloneCD kyllä tunnistaa levyn mutta eipä lue ei sitten millään vaikka pistää tuon "read only the first session":n päälle.
Tussin kanssa alan leikkimään seuraavaksi. Olen kyllä melko varma että tuota kopiosuojausta on jollain tavalla muuteltu sillä tosiaan se vanha levy meni mukisematta läpi... Prkl...

 

Enpä ole kokeillut, mutta tuo mainitsemani levy olikin ainoa jonka kanssa on ongelmia ollut.
Teippaamalla tuon sain menemään, mutta silti ihmetyttää kun aikasemmin ostettu menee ihan ilman kikkailujakin...
