Hello all. After backing up hitch my drive has been slow. When using shrink and dvd decrypter my drive functions so much slower. IE when dvd decrypter is writing a film it now writes at x1.5 speed instead of x4.0 speed.
I deinstalled and reinstalled but still slow, any ideas as to why so slow?
Thanks!!

Sounds like your DMA slipped into PIO mode.
Check the guides and you find an excellent one on how to correct this. The link escapes me right now.

Sure sounds like PIO mode to me too.

what microsoft says
Quote:
"Basically, DMA or Direct Memory Access is a system that allows devices in your computer to transfer data directly to and from RAM without having to use the CPU as an intermediary. This boosts the performance of your PC significantly as not only the device from which the data is being read responds quickly, but also leaves the most important component, the CPU, free for other critical operations. However, the UDMA or the Ultra direct memory access is further advancement over the DMA technology that uses even higher data transfer rate thereby boosting the overall performance of the PC.
For repeated DMA errors. Windows XP will turn off DMA mode for a device after encountering certain errors during data transfer operations. If more that six DMA transfer timeouts occur, Windows will turn off DMA and use only PIO mode on that device.
In this case, the user cannot turn on DMA for this device. The only option for the user who wants to enable DMA mode is to uninstall and reinstall the device.
Windows XP downgrades the Ultra DMA transfer mode after receiving more than six CRC errors. Whenever possible, the operating system will step down one UDMA mode at a time (from UDMA mode 4 to UDMA mode 3, and so on).
If the mini-IDE driver for the device does not support stepping down transfer modes, or if the device is running UDMA mode 0, Windows XP will step down to PIO mode after encountering six or more CRC errors. In this case, a system reboot should restore the original DMA mode settings.
All CRC and timeout errors are logged in the system event log. These types of errors could be caused by improper mounting or improper cabling (for example, 40-pin instead of 80-pin cable). Or such errors could indicate imminent hardware failure, for example, in a hard drive or chipset.
what Nero says:
Quote:
DMA settings - You may have DMA disabled for your CD-/DVD-ROM and recorder devices. You should enable this feature. If you have old drivers (even if you have the latest in some cases), DMA may not be properly supported, even though you can enable it. You should try with DMA disabled if you still have problems having enabled it.
Enable or disable DMA:
To enable DMA in Windows 2000/XP, simply go to your 'Control Panel --> Systems --> Hardware --> Device Manager'. Double click on the 'IDE ATA/ATAPI Controllers'. Right click on the 'Primary IDE Channel', go to 'Properties --> Advanced Settings' and change ´Transfer Mode´ to 'DMA if available'. Do the same for the secondary IDE channel.
For Windows 9x and ME, go to your 'Control Panel --> System --> Device Manager --> CD-ROM' and under the devices 'Properties --> Settings' enable or disable DMA.
and a link to a thread where you can use a "last resort" method to enable DMA if nothing else works: http://forums.afterdawn.com/thread_view.cfm/252489
Enjoy :)

Hey thanks everyone. I simply deinstalled and reinstalled my writer. Seems to be working fine!
One question I have is why would this film (in this case Hitch) cause repeated DMA errors? The disk seems to look fine.
Moreover, I have previously backed this movie up with no problems (from a diffrent original source dvd).
Could the problem be copy protection on a random disk or a bad press?
Thanks!

It was probably not the DVD that did it. Just overtaxing the system for some reason.
I did Hitch this past weekend without a hitch (pun). LOL

LOL ruger...
After X amount of read errors your drive may or may not revert to PIO mode. My guess would be a bad press.

X = 6
from microsoft:
Quote:
After the Windows IDE/ATAPI Port driver (Atapi.sys) receives a cumulative total of six time-out or cyclical redundancy check (CRC) errors, the driver reduces the communications speed (the transfer mode) from the highest Direct Memory Access (DMA) mode to lower DMA modes in steps. If the driver continues to receive time-out or CRC errors, the driver eventually reduces the transfer mode to the slowest mode (PIO mode).
Thats all it takes for windows to knock you down. You can easily get CRC errors from a scratched disc.

Cool thanks.
Hey I have another general question. After reading numerous posts, it seems that there are a few options to choose from (decrypting/encoding software). I have always stuck with DVD Shrink (encoding) and DVD Decrypter (writing the image). I have only ever had trouble with hitch (although the image did write slowly) the film plays great.
1 - I was wondering if there are others who have stuck with these two software programs and have had few issues with films.
2 - Why is it that some people have success with a film and others have trouble. Is it simply the choise of software?
The reason I ask is that it seems that someone may have trouble with a specific film that I have had no trouble with or vice versa as in this case with Hitch.
Thanks!!

Just an information: If AnyDVD is installed, Windows will no longer slip into PIO mode. Another reason to let AnyDVD run all the time.

I use DVD Shrink and DVD Decrypter for 100% of my backups, but have added AnyDVD for that extra ooomph. I did Hitch before I got AnyDVD and had no problems with it, maybe I was just lucky, or I was just holding my mouth right.

Cool, ill look into AnyDVD.
1 - Have you had any problems with backups of films while watching them on your stand alone player (after performing a succesful backup)?
2 - Basically, AnyDVD runs in the background while decypter and or shrink is "decrypting" a film?
Thanks!

I know that since I obtained AnyDVD I have it running before I attempt any backup of any DVD. Just a precaution, and it has not failed to date.
Cheers.

Ok, so AnyDVD does not replace dvd shirnk. It does however work collaberatively, correct?
Question
1 - If a backup were to fail (in this case let's say due to protection on the disk) would it be likely to fail during shink/dvd decrypter or could my backup write succesfully and just not be viewable on my stand alone dvd player?
IE - I have read in this forum that chapter 10 in the film Wedding Crashers gave some members trouble.
Thanks.

The error would come before you made a complete backup...Chapter 10 of the wedding crashers is probably nothing but copy protection code and not even a part of the movie.

Yes AnyDVD works 'collaberatively' w/ shrink - it gives it a boost that it needs for the protection it can't handle. AnyDVD is a driver that makes the disc appear copy free.
I backed up Wedding Crashers - full disc - with shrink only (nero to auto burn) - no problems. Nothing special on this one.

Thanks, I got that. A few more questions..
1 - But then when/why use dvdfab?
2 - Are anydvd/dvdfab virtually the same tool that both break down encryption in diffrent ways?
3 - So if one fails try the other? An example of my method, would this be correct?
Method 1 =
- Open Anydvd
- Open dvdshrink
- In dvdshrink , "Open disk" and continue as normal.
Method 2 =
- Open dvdfab, which creates creates an output folder similar to DVD Decrypter in file mode (I think it is audio and video ts. Sorry, I cannot remember the name excatly)
- Open dvd shrink
- Select the main movie and continue as normal
Thanks!!

Just passing again,
Quote:

Sometimes, DVDFab will rip a difficult to rip disc when DVDShrink or DVDDecrypter won't rip it. It may read the sectors more effectively.
Quote:
2 - Are anydvd/dvdfab virtually the same tool that both break down encryption in diffrent ways?
Yes and no, AnyDVD is just an encryption breaking driver, whereas DVDFab is both the above and a ripper. AnyDVD has a quicker update to new encryption issues than DVDFab usually by a couple of days.
Quote:
3 - So if one fails try the other? An example of my method, would this be correct?
Yes, that's what I would do.
Quote:
Method 1 =

This premise is good as long as you remember to Open AnyDVD, insert disc into drive and wait for AnyDVD to do its thing before you open shrink.

Yes, but you may, like I do, find it easier to create your own folder to direct dvdFab to put the files, rather than let DVDFab create the folders where ever it wants to.
I hope this helps.
