Why DVD ripping is so slow?

[Aosh]

Actually, this applies to CDs as well.

Why is it that we can burn DVDs in 6-8min, and a CD in less, but whenever I try copying that data onto my HD, it takes easily more than twice the time it takes to write that same amount of data onto the disc?

For example, ripping a DVD takes like 30-40min.

Thoughts?

your drive's rip speed is probably firmware locked

see if there is hacked firmware you can update to

I have a Plextor PX-708A

So does this mean if I'm even just copying data from a DVD i burned, it will take me 20 min?

 

[mchammer187]

im not sure about copying i dont think that should be limited or locked in anway or they could not claim
a read spead of 12x or 16x

but ripping on your drive is almost definitely locked for sure

on my sony dru 530A ripping is locked at the speed i burned it for burned dvds

and it will read/rip pressed dvds at full speed

I can think of one thing to check...

Right click "My Computer" then go to Device Manager under the "Hardware" tab. Click the plus sign next to the "IDE ATA/ATAPI Controllers." Right click the stuff under there and go to properties. Make sure the transfer mode is Ultra DMA for all channels. If it's PIO that will slow down the optical drive.

 

[Aosh]

Its on UDMA. Can't even burn at 4X if its on PIO.

So what's the difference between ripping and copying? How does the drive know if its doing one or the other? Isn't it just reading data off the disc?

 

[JackHawksmoor]

Maybe it's doing more error checking?

I believe 'Ripping' is circumventing the encryption built onto the disk. CSS, or what do you call it?

At any rate, ripping is also decently CPU intensive.

i dont think so

once the encryption key has been broken i dont think it does anything other than transfer though i could be wrong

i can rip something and encode something at the same time with no penalty so that is where im basing the assumption

When it comes to ripping DVDs for backup purposes, most drives out there will be faster than the Plextor PX-708A due to its 2X rip-speed limitation. Be aware that many other manufacturers of DVD writers put similar rip-speed limitations on their drives to discourage illegal copying of movies, so Plextor is not alone here. However, most DVD-ROM drives do not have these limitations, so if you're going to be backing up a lot of DVDs with this drive, you might consider spending the $30 or so it would cost to get a separate DVD-ROM drive if you do not already have one. Also remember that there are firmware hacks out there to remove this speed limitation from the Plextor drive, but these will void your warranty and are not supported by Plextor.


looks like you are SOL unless you are able to find a hacked firmware to unlock the ripping speed

i looked briefly but was not able to find one for you

geez, that stinks. Well, I dont do much ripping to start with, so it's not worth it for me to spend that extra $. THanks for the info.
