Decrypting Disney DVDs

[krishnan.1000]

From the forums, I understand that DVDs by Disney use RipGuard to encryption, I can make a good copy of the VOBs. But to copy it onto a CD, I have to convert it to an avi file format. Everytime I try to do that, the audio video is out of sync. Can anybody help me with that

Hi!

What software and procedure(s) did you use to rip the DVD?

If you do the following, you shouldn't have an A/V synch problem when converting:

1) Rip using DVD Decrypter v.3.5.4 in "File" mode (select "ALL" files, NOT "movie" files) and

2) Load the rip into VOBBlanker, set a new output directory/folder, select "Process all" and then press the "Process" radiobutton

[krishnan.1000]

I used PGC plugin to removed the dummy sectors, and processed them through VOB Blanker. Then I used the Gordian Knot for conversion to avi. There is still an A/V sync issue.

[setarip_old]

1) Try the specific procedures I previously suggested

OR

2) To try to isolate where the A/V synch problem is arising, as an experiment, try using MPEGMediator (instead of Gordian Knot) to convert your rip to .AVI. If this newly created .AVI is in synch, you'll have ascertained that the problem has to do with your use of Gordian Knot - either your settings or a problem with the program itself

I use GK 0.35 because it has DVD Decrypter installed along with it. My guess is that the DGIndex can not demux the audio track properly from the cleaned vobs

[setarip_old]

By your response, I'm guessing that you haven't tried either of my suggestions?

[krishnan.1000]

I am trying to copy the Shopgirl and Memoirs of a Geisha that I bought for 20 bucks each. From the forums, I find that they both have some special encryption encoded onto the disc. I used VobBlanker to clean the vob files. When I try to demux the audio tracks, all the audio tracks dont show a delay, but in the avi file, audio is ahead of the video by atleast 2 seconds. Can anybody help me here?

No help in the DVD2AVI/DGIndex forum, sorry.

You have to ask in the Decrypting forum for this kind of problem.

I'll move the thread for you.

Load the file into VirtualDub, VirtualDubMod, or NanDub.
Set BOTH "Video"(VirtualDub, VirtualDubMod and NanDub) and "Audio"
(VirtualDub and NanDub - VirtualDubMOD>"Streams>"Stream list") to "Direct Stream Copy".

A) If the difference between audio and video is constant throughout the

video:

From the "Audio" dropdown menu, select "Interleaving" (For

VirtualDubMOD, rightclick on the listed audiostream and then select

"Interleaving")
Under "Audio skew correction", set an appropriate number of

milliseconds (positive or negative) in the box labelled "Delay audio track

by"
Save with a new filename


B) If the difference increases as the movie plays:

From under the "Video" dropdown menu, select "Framerate" - and

select "Change so video and audio durations match"
Save with a new filename

Let us know of your success ;>}

As these 2 issues seem connected, I have decided to merge the threads.

Where can I get the tutorial for MpegMediator?

[freelock7]

AUTOGK2.27 can correct the delay and works with DGindex.
If desynchro A/V remains, this is a timestamp problem with the ripping procedure. Use PGCEdit to correct it.

[CWR03]

You can also correct the audio synch problem with VirtualDubMod, quickly and without re-encoding. The procedure has been listed many times.

[krishnan.1000]

The audio stream has a vbr, so I tried to sync audio and video durations. That did not work

[CWR03]

It should still work with VBR, but if you're convinced that's the problem, re-extract the audio from the DVD, compress it with CBR and mux it.

I have to ask why you are burning to CD? I'm sure there is a reason, but I just can't see it. Burning to DVD doesn't have the problems you're describing.

From what the other posters have put up, you're not having much success.

Hi ,

I dont have any DVDs, only CDs. I am looking for a good deal but no cigar
:((

[krishnan.1000]

Hi Everybody,

I repeated the process again.

I used

a) PgcEdit with FixVTS.
b) PgcEdit with FixVTS then with VobBlanker
c) PgcEdit with VobBlanker

The A/V sync is fine in the Vobs, but the avi file created after decrypting / ripping does not have any A/V sync.

Did you attempt the procedure listed above by setarip_old? It does work. You will need to follow the procedure that fits your scenario, but I would assume, given that I've had the exact same problem with several Disney DVD titles, that "A" is your problem.

I seriously doubt that the choice of media could or would play a role in audio synch issues such as this.

[VWRacer]

My point in asking about his choice of format was intended to find out why CD. With DVD ripping, and burning, the programs we normally used don't have these problems because we aren't using most of the programs that create them. I have 3 programs I use, most of the time. I have 3 alternates for stubborn rips, that get used occasionally. Out of a hundreds of backups, I have never had a synch issue with DVDs. The procedures normally wouldn't allow this. Some of the esoteric programs that are used for burning backups to CD, seem to.

A good DVD burner can be found for around 40.00 US, on newegg.com. I use a pair of NEC 35xx's, and have never had an issue with them. If you keep an eye on your Sunday adds, good, made in Japan media can be bought for around 20 cents each.

Ripguard, and ArCoss copyguard can easilty be corrected. Numerable posts regarding the proceedures, can be found here. Save yourself a ton of ongoing grief, and consider converting to DVD backups.

Good luck,
Racer
