DMA changes to PIO for all 3 Dvd drives, even after unistalling IDE driver

[Denvers Dawgs]

Ok so today I went to rip a dvd, and noticed that it was going to take 2+hrs to rip. I have 3 drives. Two internal dvd burners (BenQ DW1620 & Samsung TS-652L) and one external dvd-rom(Pioneer DVD-ROM DVD116) The problem happens on all 3. Several time I have gone to Device manager and uninstalled the Secondary IDE Channel that changes to PIO. The problem is it won't stay in DMA mode, ever, for any drive? I've treid several dvds on all 3 drives and the problem is still happening?

I'm gettting so annoyed!

It should only revert to PIO when you try to play a damaged disc. From what you describe, you have a registry problem. Uninstalling the channels won't fix that. You may need to delete your upper and lower filters. This guide from MS has the method, if you scroll down the page a bit.
NOTE: Back up your registry before doing this!! http://support.microsoft.com/kb/314060

EDIT: Another method to try: Desensitize Your Computer's IDE Channels

The following article offers a way to reduce the
incidence of this problem, although it still doesn't solve it altogether.
IDE ATA and ATAPI Disks Use PIO Mode After Multiple Time-Out or CRC Errors Occur
http://support.microsoft.com/kb/817472/ (Note: Also near the bottom of the page)
Do read this article because it contains a useful long-term workaround. But you
have to go through the procedure described here to re-enable DMA first. Assuming
you've done that, insert the ResetErrorCountersOnSuccess registry values
mentioned in this article into both the primary and the secondary IDE port
registry keys as described.

Unfortunately this is only a half solution, because when you enter an unreadable
DVD, you will get 6 errors in a row, and the IDE channel will revert to PIO
mode, but at least when you pull out the DVD in time and then insert a good one,
the error counter will be reset and it will at least be a bit more difficult for
Windows to hobble your IDE drive.

EDIT: And this is a computer problem. Moving you to the Computer Forum.

Ok so it's slightly odd. After uninstalling the driver once more. I tried to rip one of my older dvds first to see if it was because the other dvds are newer. Older dvd worked flawlessly. The movies I am trying to back up are rather new, so I first played them in windvd, and now both of them ripped at normal speeds? Sometimes pc just does odd things, to me....

You might try the 'desensitizing'. Other programs on your computer can also cause this problem. If you have some that can directly access the drives, they can affect them. Some DVD copy programs or maybe ones like Daemon Tools.
