<><> To Enable DMA back on by "uninstalling" its driver(s) by Alkohol <><>
Right click on My Computer
Click on Properties
Click on Hardware, then Device Manager
If under ?Transfer Mode? you have PIO, then you need to click on Driver, then Uninstall, OK and ?reboot/restart? your computer. Don?t worry, once restarted, Windows should automatically reinstalled them back.

Enjoy it!!
EDIT: Info added by loco
You can use the following VBS script to reset your DMA mode in windows.
Be warned that this COULD damage your computer and therefore you use it at your own risk.
http://rapidshare.com/files/14861593/resetdma.vbs.html
Instructions:
1. Despite any warnings click on the [Open] or [Execute] buttons as required to execute the file resetdma.vbs.
2. If the program found any ATA channel to reset, reboot your computer and test all drives.
3. If the problem is still not solved, set the offending channel to PIO manually, reboot your computer, set the channel back to DMA, and reboot again.

@gronimo18
As long as it doesn't say PIO Mode, then you're OK, so don't worry too much. Different hardware controllers and different burners drivers may vary on the DMA Mode, some are 5, 4 and 2. Hope this helps!

alkohol, I was wondering how the DMA gets shut off. I have been burning DVD's for several months now & have no problems till the other day, when I put a dvdrw that I did on my dvd recorder. When I put it in decrypter & starting ripping it took about 3 times as long as did before. The read speed stayed at 2.0 & below. Always before it was at about 7.0. Any way got it done & thought the dvdrw was bad, but after running it thru Nero Cd/dvd it was fine. Then looked at my primary & secondary ide channel, the primary was O.K., but the secondary channel, device 0 was on PIO.
Always on DMA mode 2 before. Clicked on Transfer mode & choosed DMA if Avaibable, but still stayed on PIO. Shut down computer, but still didn't change, so did your method & bingo it is now back to DMA Mode 2.
So what happened that it got shut off to PIO?

When windows encounter a lot of read errors it will default to pio.

Glad you've got your problem all sorted out now. Like whompus said; when you have more than 6 failed burns with Nero, Windows automatically reverse your DMA Mode to PIO Mode or Off Mode (at some point).

I'm doing great. How about you? How's Nero 7?
Yeah, I wrote this guide last November, so I can reference Newbies or those that I try to help with DMA issues to this guide, especially at this forum (Nero).
See you around buddy.

He's pretty talented indeed. However, his guide is to convert DVD into AVI though, which is the opposite of what we do (transcode/convert AVI to DVD). I don't mind watching AVI movies, since my Philips DVP642/37 is DivX, AVI certified, but sometimes it's having issues reading them AVI or DivX directly from the player itself for some odd reasons. Therefore, I would rather have Nero Vision to transcode/convert all of my AVI movies into DVD, so I can enjoy them movies on my big screen 55" Widescreen SONY HDTV with my sons. Most of my AVI projects are "anime and or Japanese animation series" only.
In addtition, I'd already knew how to "import/convert" DVDs (movies) into Ipod, which I think is awesome. I've just finished imported Madagascar and House Of The Flying Daggers (both are awesome movies) into my Nana Ipod 60GB last week.
I might put on a really nice and simple guide on how to "import/convert" movies/dvds into Ipod using Nero Recode 2 and Nero Digital later on when I have the times.
Have a great day and enjoy backing your AVI projects with Nero Vision.

I too have had probs with the DMA being off and have followed this thread.
However, when looking at Nero Infotool, I do not have a line which says "DMA ON", but do have a line which says "Autorun On"
Should this work? and if not, then is there another way of getting the DMA onto the "On" position?

What does your Primary & Secondary Channel said? That's what it counts, if it says PIO or Not available, then you still need to "uninstall" it's driver(s) Look at picture for reference:

Another thankful reader.
I've been burning successfully for a couple of years. A couple of days ago I made my first movie from an AVI file off of my digital camera (and tried to make a DVD). I got horrible results (choppy audio). The image on the hard drive was fine. Then I discovered that I could not successfully burn CDs, either (see below). To complicate things, when I did a full erase of a DVD+RW (to do some testing), Nero completed the erasure in 17 minutes (normal for 4x) but then hung (had to kill it in task manager). It left my DVD/CD burner so locked up that I had to reboot my system (Windows XP) to use it again.
I ended up spending the whole next day (today) troubleshooting my drive (Sony DRU700-A). While seeing if I could burn data DVDs (ISO), I noticed the burn taking forever (27 minutes for 2.5MBs). Then CD check took 24 minutes to read it - while using almost all of my CPU. That's what brought me (indirectly) to this post.
Now I believe I know what happened. That CD coaster was caused by a bad batch of Sony CDR's (starting at about the last 15 of a spindle of 50). I had burned a backup of some files to CD before I did any of the above and created a coaster (locked up CD Check when I checked it). In the process, Windows must have knocked my Secondary IDE bus into PIO only mode (something I finally realized after reading this - and now recall having to deal with once before, a long time back).
In the end I followed the above procedure (uninstalled my Secondary IDE bus drivers) and it solved all of my problems. I have re-burned the home video successfully, my burn speeds are back up to normal, and CD check runs normal.
Those bad Sony CDRs are a real disappointment (Sony's are one of the most dependable brands of CDR's I've ever used), but I can live with that. I got them on sale for about 20¢ apiece (two 50 count spindles for $20) and I don't use many CDs these days.
So .... I'm adding another thanks to Alkohol for posting these clear instructions. It pulled me through. I was sure I had a bad drive, but this procedure fixed everything.

If you did exactly as stated by the guide (i.e. "uninstalled" your drivers), then Windows should re-installed back and reversed it back to DMA Mode or DMA available.
Unless you're the few that has a Nvidia drivers, then you may need to tweak a little deeper. I can't remember where, but if you do a search then I'm pretty sure you'll come across an answer.
