Help ! DVD Decrypter too slow ???

[Xeixe]

Hi !

Now i finally got a DVD-Burner. I wanted to test it, so i decided to burn one of my movies. I chose the Walt Disney movie "Lilo & Stich". I used DVD Shrink and didn´t have any problems. But it took 3 1/2 hours to make the backup ! I thought it should work faster. for compressing the movie, DVD Shrink took 1 hour and 15 minutes. I think that is okay, because I only have an AMD 900. Well, but it also took 1 hour and 30 minutes to decrypt the movie to harddisc. I have the NEC burner 1300 A, 4 x Speed reading an burning DVD´s. I thought that the decrypting-process would only depend on the speed of the burner. Other people only need 15 minutes to decrypt the movie. Well, than i tried to decrypt the movie first with DVD Decrypter instead of using DVD Shrink to decrypt. But DVD Decrypter also needed 1 hour and 25 Minutes. Is there something I´m doing wrong ?

A second question: Is there a possibility with DVD Shrinkt to keep the menues, but to delete certain extras ? For explame I would like to keep deleted scenes, but delete the making of.

i hope someone can help me.

Bye, Emilio

don't use a dvd writer for anything apart from writing!
they are not very good at reading disks fast.
put in a liteon dvd rom and use that to read from.....much faster.

Well, but I don´t wanna waste money on buyuing a liteon dvd only to save some time at reading. I mean, a liteon dvd reads I think with a speed of 16x. My burner with 12 x speed. The difference shouldn´t bee too big. I can´t imagine, that using a liteon DVD, the ripping takes only 15 minutes and with my burner over an hour ...

I have even read an article about ripping a dvd. It said that it would be important to have "DMA" on at the settings of the DVD Burner. When i ripped the movie, DMA was not on. Could this be the reason why the ripping was pretty slow ?

[Hiro2k]

Yes that's part of the problem. UDMA allows your hardware to access your computers memory without sending a request to the processor, so it saves time. And when your transfering lots information from one drive to another, it only makes sense to have it on, otherwise your wasting to much time sending requests to the CPU.

But the fact is that the 4x difference between the two drives isn't what makes the liteon faster. For instance, some new Pioneer drives have intentionally limited speed by ripping. The solution is to modify the firmware - if it exists. So it might just be that the manufctureres of your burner limited the reading speed of your DVD drive. I don't know for sure, but it could be a possibility.

Also be aware that the ripping speed can be up to 16x - only at end of single layer DVD. But dual layer discs usually can't go over 10-11x.

Read my post here (http://forum.doom9.org/showthread.php?s=&threadid=44077) in the "questions for upcoming newbies faq guide". It basically covers your problem, and make sure you read the links I added.

Your problem isn't new, many have posted about it before, most do what sarahjh69 said to do and buy a dvd-rom solely for ripping.

Like Hiro2k said make sure DMA, or "DMA if available" is checked. It could be your biggest problem, you should have it on anyway since it's a dvd-writer. I'm surprised your not posting about coasters.

Also, the speed and age of your HDD can play a major role in ripping speeds.

Apart from the DMA issue, it really depends on your burner and its firmware. Take my Toshiba SD-R5002 - it happily rips dual-layer dvds, maxing out at >11x. Clearly no need to get another drive there.

Before you buy a dvd reader for ripping, check its ripping capabilities. Some drives are intentionally capped at 2x or so when reading CSS-encrypted discs. Sometimes modified firmwares are available (again, certain Toshiba readers come to my mind).

Thank you all for the helpfull coments. I would have one last question ? I have a CD Driver and my DVD Burner. The CD Driver is master, the DVD-Burner Slave. Does this setting influence the ripping speed ? Would it go faster if the DVD Burner would be master ?

[flanman]

Usuall the ripping speed is preset by the manufacture. Changing location on the IDE cable will not help. Here is an example. I have Sony 500AX that is a 8 X reader, but only rips at 2x no matter what. However my Liteon 411s is a 12x reader and will rip at close to that speed. It all depends on what the manufactured of the drive had capped it off at. Not much you can do to speed it up other than using seperate DVD rom drive for all ripping.

the manufacturer has set 2x to max dvd-ripping speed.
no dma helps here or any other trick than to use hacked firmware.
my nd-1300a after reflash now rips at happy 4-6x speeds
(and accepts 30+ more dvd-r brands than the retail).

if you're wondering where to get these modified firmwares,
look no further:

I flashed my ND_1300a with new firmware and it improved it no-end.

I also use a normal dvd drive for ripping, it`s usually faster and I won`t wear out the mech in my burner as quickly!

It has no influence on ripping speed, but you'll have problems to copy data on the fly from your CD drive to your burner I've learned because access to the drives on one IDE Cable is only granted exclusively. That means, while you read from your cd drive you can't write at the same time.
You should consider to put your cd drive an secondary slave instead or, if alone on secondary, as master.

I was told once upon a time that if I try an on the fly copy with 2 drives on the same IDE it will encounter difficulties like u just mentioned. However, when I tried it, I found that it works brilliantly. By that...I mean it will copy a DVD5 in about 13 minutes without any errors or glitches. Perhaps some hardware setups have issues with that, but not all of them.

CDRW/DVD-ROM is master
DVD+RW is slave

My 2 cents.
