I don't see how it is possible for an audio Cd player to play a cd flawlessly, but a cd-rom will fail to The error correction is all in the hardware, not the software, isn't it?

Not quite. The difference is what happens when the an 'uncorrectable' error is encountered.

Protected CDs contain many thousands of uncorrectable errors which are deliberately inserted during recording. On a PC the drive will send what it could read and verify, along with a message saying whether the data is correct or not.

On an audio CD player, if the audio decoder receives a message saying the data is incorrect, the decoder will attempt to fill in the gaps with what it guesses will sound OK (it interpolates between known good areas).
Rippers simply get the sound with the raw data, and an error count, but don't know which bits of data are the errors, so can't cover them up.

If you are fortunate enough to have one of the very rare CD-ROM drives that can interpolate while ripping then you should be able to rip the CD straight off (if you use 1x ripping).
If you don't, then to copy it you'll need to play it in analogue mode, and record the analogue signal with your sound card.

If I recall, the "latest" drives that can do this are the 16x/24x/32x/48x/52x lineage of Lite-On CDRWs... Not including current 52x production, only early units.

That is one thing that has baffled me... why has no person or group brought suit against Sony and the other companies that infringe on every consumer's Fair Use rights?

It is not new copyright protection, its the same old sh!t. EAC worked just dandy on Linkin Park - Meteora, which was "Copy Protected".

return it. do not support such tactics. they are effectively sh*tting in their paying customers faces. it has no impact on real piracy

Yep, if you have auto-run on even once with the CD it'll install a device driver without telling out. After that you can't rip the disc, without at least disabling the ninja device driver.

The link provided above shows show how to disable the device driver.

Yes, return it, but only after you've figured out how to rip it:evil:

don't rip it - just browse the disc and find the wav files, copy them to your HD, and then LAME em.

If the disc will play in a regular CD player, you can get the undistorted data off and put it on your own media.

huh?? to play the cd.... u have to use the player on the cd

no


???

1. Will this disc play on my computer?

Yes. This disc is compatible with both PC and Mac.

PC Users: When listening to music directly off the disc, you must use the player provided on the disc. Attempting to play the audio on the disc (while the disc is spinning in the computer drive) with another player (i.e. Windows Media Player, Real Player, iTunes) will result in distorted sound.

ignore that

I have a surefire way for getting digital music from protected CDs onto my 'puter. I play 'em on my standalone CD player that has digital optical out, and record on my PC sound card with digital optical in. :)
