Ripping speed

I upgraded the firmware on my NEC3500ag to TDK 1616n v2.C8 SE. I use the Ritek 4x and burn at 8x without any problem. I use DVDShrink 3.2 / Nero 6 to rip/burn. Burning is at 8x (via USB 2.0 and external case NEC3500). However, the DVDShrink ripping part, it’s slowest. I only get 3900kbs MAX. I thought I can rip it at 7x (as the firmware said) and that should be a lot faster than 3900kbs??? What’s wrong?

DVD Shrink has to transcode on the fly as it rips your disc, it’s therefore to a large extent dependent on your overall system speed. You don’t however mention your setup. :slight_smile:

I have the same issue with this drive randomwalk, my 3500ag rips very slowly, 3.5X max using DVD Decrypter while my Plextor 712A rips the same DVD at 12-13X on the same system.

My system is an IBM ThinkPad T42 laptop with 1.7M GHz, 1,000 MB memory. While ripping, CPU level usage was only around 50%.
I’m thinking there is something wrong with the drive/configuration/firmware for ripping speed??? Please share your thoughts. Thx.

My guess…faster the processor…faster ripping speeds…and of course RAM…drives only gonna go as fast as the processor will let it…4.7gigs alotta info to process by todays standards.

Just out of curiousity, I did a totally unscientific test on my computer as I have 3 different types of hard drives. I used DVD Decrypter 3.5.1.0 on a home movie of 4.5gb on a single layer dvd+r booktype set to DVD-ROM. Both ide drives are on the primary channel at UDMA-5. The 3500 is at UDMA-2 on secondary channel. MB is a P4PE 2.4 Intel, 512 mb ddr Crucial ram. I was looking for the fastest rip speeds while ignoring CSS and DL.

I found it interesting the 3 minute difference betwwen the fastest and the slowest drive.

I’ll post a dvd9 tomorrow if anyone is interested.

you can look at the specs of your hard drives all you want the udma 5 drives should keep up with any scsi drive… but I create dvd’s from tivo movies and it takes some processing and I can tell you that by far my quantum atlas 10k scsi drives 160 are much master than my udma 5 ata drives…

Second test. Seems using a DVD-ROM would be better for ripping!

I used DVD Decrypter 3.5.1.0 on disc 1 8.2gb DVD-ROM The Abyss. Both ide drives are on the primary channel at UDMA-5. The 3500 is at UDMA-2 on secondary channel. MB is a P4PE 2.4 Intel, 512 mb ddr Crucial ram.

It appears that hard drives in this case make no difference in rip speed. What we need is a rip from a virgin 3500 to compare.

Here is a good review of DVD RW drives, the NEC3500 being one of them. It was terrible at ripping and got low scores.

Try ripping from a single layer source. As Dee mentioned you are Shrinking/compressing a DVD video most likely and you didn’t specify the source size/compression/etc. There will be a huge difference if the source is a 4.9GB vs 8.7GB video if all you do is counting the time it takes.

I fail to understand why the 3500 continues to get slapped around as a poor ripper… It’s best rip drive I’ve ever used!

Single layer full disc ripped with Nero:



PC-Doc, what FW are you using ?

Tdk 2c8

the first screen states the disk is not encrypted, am I reading that wrong.

Thanks Doc !
Edit: does it have the riplock removed ?
A: = yes

I’ve seen those kind of speeds, but only on an SL disc.

I am myself the owner of Lite-On 411S@811S and NEC ND-3500AG, please don’t misunderstand me I like my NEC dive very much and satisfied with, but I have not been able to rip any DVD even at rate of 6X. I am using DVD Shrink in conjuction with Nero and 2.16 firmware.

Then update the firmware…

The problem is that there is any concrete avidance that changing the dirive (ND-3500AG) firmware to the third party (MadDof, TKD or any Mod ) firmware will result in ripping speed, writing speed or even reading speed performance in drive. That is why I am still using stock firmware 2.16.

Go here: http://tdb.rpc1.org/#ND3500A
And you will find that for each firmware version release there is a hacked version with the Riplock removed…which you do not get with any original firmware.
There is a reason why TDB/Herrie/Liggy/etc…spend all their time hacking these firmware…removing the Riplock being one of them.
Most CDFreaks members will tell you that yes there are concrete enough evidence that if you use the right firmware the Rip speed will greatly increase :slight_smile:
