@grug2k: What did you mount the ISO with, or did you actually burn it? |

I made the ISO using Nero. I just made a DVD-Video compilation, dragged the DVD Decrypter output into VIDEO_TS, the dvdaripper output into AUDIO_TS, made an .iso using Nero's Image recorder, and mounted it using Alcohol 120%. (Although Daemon Tools or Nero Virtual Drive would work too).
Once its done, I just mount the image, load up WinDVD via ppcmripper and direct it to the virtual drive. |

Watermarking is the problem
I did some ripping on my DVD's the hard way:
I plugged the analog out of my Marantz universal player to a high quality audio card ( EMU-1820M, that I use mostly to translate high quality vinyls to 192K DVD-AUDIO), just to see how it worked. Since I was interested only in backing up high quality Stereo I did a 24/96 PCM copy of a DVD ( Buenavista Social Club, Ry Cooder, Compai Segundo). So using wavelab-5 I did a DVD-audio ISO file and burned a disc. What happened: every track pleyed for about 30 seconds and then the DVD went to stop: This is watermarking in action. So I did a blank movie and put the original 24 bit file, spliced in tracks as its soundtrack and burned it as DVD-VIDEO. I played it again and.... It worked!.... No watermark checking in DVD -VIDEO to the soundtrack wave. What about multichanel?, well that can be solved also, without not too much loss, by using DTS. Again, use the DTS track as the soundtrack on a blank VIdeo, and you'll get the highest possible quality of a watermarked source. As far as I know, there is no software available up to now to erase watermarking. The really interesting about the ripper is that it will save you some time, because I may say that the 24/96 copy using the EMU 1820M card is the closest you can get to the original. I bet nobody would be able to hear any difference. As for some people here wondering why taking so much trouble having an AC3 track I must say they should go to some high end shop and spend one or two hours listening to a DVD Audio on a high end setup, and then come here and give their opinion again. (Take with you some of those for example, Buenavista social Club, Ray Brown's Soular Energy, Mana's Sueños Liquidos, Pat Metheny Imaginary Day, Eagle's Hotel California, ELP's Bran Salad Surgery...) Mp3 and ac3 sucks in my opinion. The only lossless compressed scheme I like is DTS...so far, but nothing comes close to 24/96 and 24/192, only vinyl comes close, when mastered using 1/2 speed and pressed using 180 or 200 gram baffles; and then played on a high quality set-up ( excellent MC catridge, excellent phono preamp). Of course the rest shall be high quality too, because if not, why bother in the first place. Francisco |

Okay, AC3 audio is not in the same league as the audio stream on an DTS CD or even an DTS DVD but as long as the frequency range is something like 20Hz to 18-20kHz and the dynamic range extends to a min of 90db, I reckon given the bitrate, AC3 should work perfectly well. Can anybody else confirm though? Cheers

AC3 is like anything else....it's all about bitrate.
IMHO,a stereo 192k AC3 file sounds better than the same in mp3... But,do the math.....448k/bits for 6 channels vs DTS @ Cd speed (lossless@ 1.4 megs). No contest. I'm glad with BRD and DVD-HD we get lossless formats. Cheers!

I reckon that if the DVD audio is decoded into Wave files, re-enconded as a DTS Audio CD or even a DTS DVD with hi res (96khz) sampling at max datarate (about 1.3mbps) would blow away the any AC3 file...
I realise the quality isn't as good as DVD AUDIO, but it would be far better than Ac3 and easy to play on your home dvd player.... What do you guys think? |

DTS-CD is not lossless and it's still a relatively pawltry 16bit 44.1khz.
Also, AC3 @448kbit has full extension to 20khz whereas DTS DVD @768kbit is only flat to ~16khz and then trails off. Neither is even vaguely comparable to the lossless 24bit DVD-A/SACD formats. Regarding ripping to a 6 channel lossless 24bit wav, how would you play it later and output the 6 channels to a receiver? |

That reminds me of a time when there was software that attempted to read DVD's using CD drives. I think it would attempt to read how the CD-ROM drive's laser would bounce off the DVD disc and try to interpret it into real data. This was back in the day when DVD drives cost about 300-400 dollars. Wow, I'm starting to feel old. |

...and it's gone
I got a phone call from a big local lawyer office (no fake, I checked the caller ID and the phone number really belongs to a lawyer office). They have been hired to make me stop distributing the DVD-A tools. It was a reasonably big talk, but I can summarize it with They: we are giving you two choices, either you remove all references to those tools from your site now, or we'll have to take you to court. Me: I'm already removing! They: Thank-you for your cooperation. Oh, well. It's been fun. I'm amazed at how well it spread in these two days (!), and I'm sure from now on you'll be able to find those tools in countless mirrors, p2p and the like. Shine on! R. |
