It'll work fine & I do it all the time before I decrypt & rip DVDs. |

It WILL make an exact copy of the DVD onto the drive (assuming DVD |
| 26 |
video, and no ARccOS [1]), it will just be an exact copy of the |
| 27 |
*encrypted* movie. It won't be playable without an additional |
| 28 |
decryption step (although mplayer can include this step |
| 29 |
automagically), but it will be an *exact* copy. |

The OP is talking about DVD-audio, however. It is less clear to me |
| 32 |
whether this is playable under Linux [2]. If it is then I would be |
| 33 |
trying to rip it as some kind of playable audio - I agree with the |
| 34 |
other comments (a point you're also obviously trying to get at) that |
| 35 |
there's little point in storing an encrypted copy. |
