question about rip speeds

[smokiespliff]

Hello!

in short: do rip speeds depend on cpu and/or hdd speeds?

i have an old banger of a computer (p3-600), but it works! i get rip speeds with dvd decrypter averaging 2.0x, but it can go as high as 2.6x (i have DMA enabled and latest firmware from manufacturer - don't want to risk "unoffical" fw)

i know its slow, but it suits my needs, and i just assumed that it was slow due to my old crock of a machine.

but having read this:...
"In the following I'll give you two examples of average ripping times and speeds. This is only depending on your installed reader/burners capacity - not CPU or memory have any impact on this."

...which i found here (http://forum.digital-digest.com/showthread.php?s=&threadid=47035) i started thinking that it has nothing to do with my cpu and/or hdd, and its a problem with my dvd-rw?

i've got an Aopen DUW1608 which should give rip speeds of at least 8x.

Thank you!

i'd got up to 8x on my old celeron 500 (keep in mind the speed builts up toward the end of the rip)

i remember reading something about a speed limit on dvd-rw, or maybe i'm thinking about the PIO in XP

other versions of dvd decrypter "might" rip faster than other

look at your cpu usage whilst ripping. If it's on 100%, you know your cpu is the limiting factor (or DMA IS an issue). If it's not, the problem is with your drive not wanting to rip any faster.

sorted it :)

when i got the drive, i took out the slave, and put the new one back in as the slave... i changed them about to see what would happen, and presto! it started ripping at 3.8x and slowly made its way to 7.8x! (which i think is just about top speed)

i knew the burner is recommended to be the master, but i didn't think it mattered that much!

thanks anyway!

Just wanted to share. I got a fairly new DL burner. Quality matters so i cap my burn speeds at 4X. I noticed alot less of those mosaics in the frames this way. And i get a more stand-alone friendly dvd. Done alot of testing with other friend's players. Seems 4X is the way to go.

My own experience leads me to believe it's not so much the dvd player/burner (though it can be an issue if your burner/reader has rip locks built in), but it depends on the structure/length of the DVD. I can rip up 16x on a single layer dvd and about up to 8x on a double layer disk. If your DVD is greater than 4.5 gigs, it is a double layer disk, less than 4.5 usually means single layer.

On a single layer DVD, my ripper gets progressively faster until near the end it reaches 16x. On a double layer disk, it goes up to about 8x at around mid-point of the rip and then goes slower as it progresses toward the end of the rip.

Another big factor is how clean your DVD is, if it is dirty, the reading laser has to slow down to get a better read of the data.

BTW, I have the Lite-On combo drive.

Yea...mine seems more the quality of the blanks. I set it at 4X just so i don't waste time having to do it over. Ripping isnt such a big deal as far as speed goes. I use either combo for that.
