Smartripper vs DVDDecrypter

[Mars-L]

Hello,

While ripping Crouching Tiger both Smartripper and CladDVD stop after 260 MB of the first VOB with Smartripper mentioning it needs the CSS-key again (even though I played the movie before ripping). CladDVD just stops with that VOB and goes on with the next VOB just leaving a incomplete first vob.
So in my last attempt to rip it I searched for another good ripper and found DVDDecrypter......
YES, it entirely ripped the whole movie AND....even twice as fast as SmartRipper and CladDVD. While these just got a speed of 1.2 at really max, DVDDecrypter reached over 3.5 speed going up to even 4.0 x. Anyone can explain this.
Looks like DVDDecrypter is better then the nr. 1 and 2 of the rippers.....

Is DVD Decrypter updated? I ask because it matters for CSS decription, which is updated every now and again (I haven't followed progress fo this program and I've never used it, so I don't know)... does it have features like writing fresh .vob files? (like you select chapters 1-4, and it merges them based on "max filesize"? I'll have to try that out.

I can just say that I have never had a real, fatal problem with Smartripper (2.26 anyway), I do notice it never gets past 1.5x speed, but I do have a fairly slow DVD-Rom. The keycheck problems you've had probably have more to do with HOW OFTEN Spartripper checks the key. Usually "keycheck once" will work. If not, do "by .vob". And if not that, try "By Chapter". I've never seen it by any smaller increments.

Sometimes if you check too often (by .vob), it will not find the key for all the .vob files (in some older versions). But, if you leave it on "check once", it will go on through and get decrypted.

I've also heard to never, ever use CladDVD or DOD Speed ripper, though this might have been updated, but I've heard that these two proggys don't have updated CSS Decryption.

Hearsay !
CladDVD does do CSS Decryption and sofar never gave me problems always came up with the key. Including Crouching Tiger.

Whether DVD Decrypter is updated I don't know, but it did do the job well on Crouching Tiger which is pretty recent. The latest DVD Decrypter is of March 2001.
Concerning decrypting the VOBs of Crouching Tiger, I tried it all, no CSS decrypting at all, every VOB, just once, even every chapter, every VOB id and the other options. NONE worked on the Region 2 DVD.
The only options DVD decrypter gives is ripping the entire movie or by selecting the files, you cannot select chapters/cells. But that's not needed when you wanna rip a movie IMHO.

new technology (even though i only heard it was implemented in some disney DVDs i.e. jungle book) each vob may have its own specific CSS key...so in smartripper...under settings...try setting it to obtain CD key for every vob instead of once

[vitualis]

The same is true with DVD Decrypter. Indeed, it was the first ripper to to able to search for a new key at each new vob and cell id (but I believe Smartripper can do this too).

Mars-L, I apologies if I misunderstood your last post... but there are many reasons why you should rip the WHOLE movie, not just a specific video and audio track. Firstly, you must do this if you want to use FlaskMPEG. Secondly, when using FlaskMPEG, this gives almost foolproof (and easy) access to subtitles.

As for you first post on why DVD Decrypter appears to be faster, it is because it rips the WHOLE vob, while by default Smartripper rips only the specific tracks (MOVIE MODE). This is slower. If you use Smartripper on "file mode", it should be just as fast as DVD Decrypter (at least somebody else reported that this was so when he tried it).

Regards.

Virtualis, I always rip the full movie, meaning the IFO and all VOBs excluding the zero one. Besides I also always use the FILE option in SmartRipper and CladDVD where I select the needed files, but but still it's slower compared to DVDDecrypter. (But indeed I also assume it's one or another setting misstake)

Thanx for the hints
I'm still curious what causes the speed difference, probably need to experiment a little more.

When I use Smartripper, the file mode and "movie" mode are the same speed. Both are ripping the same files, and are removing macrovision, decription all the while, so shouldn't be different..

I'm not too upset with the speed, it's still only 35 min. for a whole movie to rip... I can deal. I might try out DVD Decripter just for a test drive...

It is still a mystery why there are such large differences between people in the speed of ripping a DVD. However, for some people, the FILE MODE vs MOVIE MODE makes a big difference.

There can be a big difference between the two because the decrypting program doesn't have to do as much analysis of the vob files when decrypting in file mode. It is basically just recreating the entire structural organisation of vob file with the decrypted video data rather than the CSS encoded one. With "movie mode", the proggy has to determine which part of the vob file relates to the specific video and audio tracks wanted before decrypting it.

Again, I state it is unknown why there is such a large difference in time between the two for some people and not others. Perhaps it has something to do with increased+inefficient random disc access for some DVD-ROM drives/drivers/chipsets??

Actually, this is quite slow... How fast is your drive?? As a comparison, on my fairly old 8x Hitachi DVD-ROM drive, I invariable can decrypt an entire DVD (menus and all -- i.e., close to 8 Gb) in less than 20 min.

I've got a Delta 12x (on secondary master by itself) and it only rips at 1.9x (aveage). I've been reading old posts to try different things but I can't get over the differences in rip speeds for different people. I'm running a K6-2 500, but I've seen post where people have win98, 8x DVD, 233MHz and rip at nearly 8x?!

Does anyone have any suggestions for speeding up rips? Do the IDE cables matter? What about DMA (for DVD-ROM, HD or both)? etc? etc?

I ripped CTHD 2 days ago with the latest version of smart ripper successfully. I'm not sure how well my compression will come out but the rip went through with no errors. Good Luck.

I think mine's only a 6x or maybe less! Would that explain it?

Like I said, no big deal. Now, If I could only encode one perfect VCD, with perfect, fluid motion and a low bitrate... {sigh} now that would be the life...

DVDdecrypter Hole Movie (1hour55min of play time) Vob files 7 1048574kb each round about rip all in 13min 52sec , DVD2AVI each vob in about 1min 12sec , TMPGENC Palvcd layout 3Vobs(*.d2v)+Audio(AC3 384kbs 48khz *.Wav) =2480924kb save as MPEG , Encode time about 21/2Hours mpeg size 629meg Just right for CD (1hour 1min Video play time)Next CD....Most DVD's Take 3 CD's with all the added bits on as well..
1.2 Athlon DDR
512mem DDR
ATI 64vivo DDR
80gig HD
and so on. So yes use DVDdecrypter very very fast for me all vcd's decripted and demacroed and quality same as DVD.
