DVD Shrink now 33% slower?

[madoka5]

I use DVD Shrink 3.2 on a Cele 2.8. I noticed a suddenly increase in time to rip. Found that before I was using a rate of approximately 3,000 KB/s, and now it is down to 1,900 KB/s.

I've tried swapping memory and installing more of it, trying different drives, and trying different discs all with no effect. Any clue as to why this happened?

Thanks in advance!

Check if DVd drive is using DMA or PIO.

[madoka5]

Yup! Thanks a bunch. It was set to PIO. What a stupid XP "feature." And they make it so complicated to change it back as well.

It's not an "XP" feature, been around in most if not all the windows versions. ;)

WinXP will automatically downgrade the Ultra DMA transfer mode to PIO after receiving CRC errors, which means that you have stability problems with the ATAPI device, or you have mounted improper cabling (for example, 40-pin instead of 80-pin cable).

Try uninstalling the device and then reboot to automatically installing it again

umm, searching for "pio udma" in the hardware forums is likely to yield many answers. So will a well formed google search. I suggest you familiarize yourself with rule 1 as we don't look too kindly upon people who ask questions first, and only search when being told to.

this is just one of many reasons a few years ago I went from winxp back to win2000. Now I'm forced back on winxp and will have to watch for it flipping to PIO 'cuz it knows better than me' and like mcdonald's 'we do it all for you'.

Not 100% sure - but I have a feeling that SP2 will let it stay in DMA mode and not revert back to PIO mode after x read errors. I think installing SP2 is one of the 'solutions' in the Microsoft Knowledgebase regarding the PIO problem.

That explains why my drives are still in DMA mode even after several dozen read errors on both drives when trying to read a scratched disc last week. I double checked after reading this thread.

[cynthia_old]

I noticed this my self after 1700 read errors with DVD Decrypter on a test with ARccOS discs - still DMA mode.

By the way - welcome to the Windows XP club mrbass... :rolleyes:

I found this to be an interesting discussion as I did checking on DMA and PIO in my Toshiba notebook and phoned Toshiba Support regarding this as my notebook is still under warranty.
They advised me that the settings could not be changed as they were set by the system since I have a notebook and the settings relate to the notebooks CD drive and can't be changed to suit my external BenQ 162I that I use to do all of my backups.
Does this make any sense??

I would appreciate comments, as I am a Noob and have just done a lot of reading on DMA and PIO.

Cheers

can someone explain how to get to this DMA and PIO stuff, all this talk is not english to me. i'm also having problems with shrink being too slow although my other programs(dvd2one,intervideo,dvd95copy,1clickdvd) work fine and very fast. so since these do work fast, do you think that i have a computer problem or a shrink problem? thanks.

mrbass just posted a link on how to do it in post #8 of this thread.

Only difference in XP is when you right click "My computer". In XP go to "Start"
then scroll up to my computer, right click my computer, then hit the properties tab. Go to "Hardware" tab then click the "Device Manager" button.

For the rest of the process read the mrbass link posted above.

Does this make any sense? No, as I have a Toshiba laptop with WinXP SP1 and have no problems changing to DMA from PIO which I have had to do on occasion.
