How to copy_rip DVD-Audio Discs for sharing on Demonoid.txt
Thanks to the generous people at eMule.
There are 2 key technologies involved in securing the DVD-A audio:
watermarking (not always applied to the audio).
The encryption has been broken, but the watermark still exists in the audio stream, and if the DVD-A player detects that the watermark doesn't match the DVD-A disc (eg you've made a "backup" of your DVD-A), then you only get about 30 seconds of audio before nothing but silence.
The applications use WinDVD:s licensed DVD-Audio and MLP decoders to access the unprotected data, which can then be freely shared. The only caveat is that DVD-Audio:s Verance digital watermarking, embedded in the audio signal itself, cannot be removed. The Verance watermark contains seventy-two bits of data comprising four CCI (copy control information) bits and eight usage identifier bits every fifteen seconds plus sixty content identifier bits every thirty seconds : if a DVD-Audio player detects that an embedded watermark does not match that of a specific disc (in other words if ripped DVD-Audio content is burnt to a blank DVD-R disc using an authoring program such as DiscWelder BRONZE), the machine will halt playback after thirty seconds.
Only seems to be half a crack to me as you cant get a direct copy, you get only first 30 seconds before the player stops playing the disc's.
These DVD-Audio Players have no watermarks detection:
These DVD-Audio Players have watermarks detection and stop sound after 15-30 sec playbacking:
You can play ripped and watermarked DVD-Audio on your PC
by CyberLink PowerDVD with no problems.
But InterVideo WinDVD supports watermarks detection!
So I must notify in advance about watermarked DVD-Audio.
VIDEO_TS (DVD-Video Part) has no protection by watermarking, of course.
I used a few methods to burn, using a few programs, but the best result, IMO was using ImgBurn, in 'build mode'. Place both AUDIO_TS and VIDEO_TS folders in the same folder, let's name it DVDA and nothing more in there. Then simply drop the DVDA folder in the source panel of ImgBurn and burn it to a DVD-R. It's as simple as that. A simple guide you find here: http://forum.imgburn.com/index.php?showtopic=1779
