DVD Fab DVD lovlevel Treiber
It is part of the install of DVD X Copy from what I can tell.
Its for DVD decoding, used by DVD copy prgs such as DVD XCopy Platinum, etc. harmless & necessary for these prgs to work
Part of DVD Xcopy can cause Stop errors in XP system . If that happens disable when not using XCopy .
  Jesse Silverglate  
It installs with VSO DIvX to DVD. Everytime I've installed it, playing dvd's and cd's lag horribly.
It comes with DVDFab Platinum
It was required to install my PSP Video Vault software, which can rip from DVDs.
Pcouffin is part of the Patin Couffin Layer for Dvd/Cd copying developed by VSO software for apps like DvdXCopy, DvdFab, etc
it a process that comes with dvd applications...harmless really
It is a DVD decoder / driver for viewing movies. It does NOT de-encrypt CSS.
Installs whenever you install most DVD copy program

It is a necessary part of DVDFab Decryptor Platinum
This is not from DVD X copy, because I installed it my self, it's a "paten couffine driver" used for decoding Movies, Leave it, it's fine :-).. You can add or remove it at any time with the "patin checker file" as needed while recording or not. You can also find it at this link above, but hush is thw word..

cd/dvd driver for vso products (ConvertXtoDVD, etc.)

A piece of crap...stops XP from a repair install

It is a secret log kept by the FBI as part of its anti=piracy measures.

if you are using DVD x Platium and you put dvd fab on you will not be able to use Platium again without some problems in short it will mess up ANY DVD and require to reinstall it best answer if programs like DVD X Platium are working ok do not install DVD Fab
for dvd decoding and encoding
Is a part of the installation of Clone DVD
resident in my device mgr also .. do believe it is with dvdfab or such .. could this possibly be a virtual drive also ? .. my call of duty 2 single player wont run ..detects an emulator running /instaleed ... I can t not Find Any Emulator software running anywhere .. except for this pcouffin thing !
Low-level CD-ROM driver installed by ConvertXtoDVD, is buggy and makes your system BSOD with PFN_LIST_CORRUPT 0x000004E error. Get rid of this software, there are hundreds of alternatives, besides an AVI-encoding application has no rights to start screwing with low-level cdrom drivers anyway.
when installing CloneDVD this installation wrote to this it had previously expired as a trial ver., I thought to uninstall and clean registry, then reinstall..wondering where the time counter was kept....I still don't know... try using What's Running prgm to see how anything else accesses pcouffin.sys
part of DVDFab Platinum DVD ripper software
from DVDfab
Used in many programs, especially DVD and Codec software, needed for some video types to play, leave it alone.. WMV (DRM), WMA (DRM) , WMH, WMVHD and MP4HD will not play if unloaded/deleted.
It's a dvd burning/decoding file
Comes with DVDFab, I think
  Ivan Rudakov  
It is installed by Plato DVD Copy

DVD decoder used by ConvertXtoDVD

ConvertXtoDvd installation

comes with covert x to dvd
DVD decoder used by ConvertXtoDVD
  Fernando C.  
it started installing when installing 1 click dvd
Feeding this file to the "XP Installation" repair process allowed my repair to complete porperly. I simply found the driver "pcouffin.sys" on a known good instalation of XP that had "DVD Xcopy Platinum" and copied the file over by burning it to a CD.

CloneDVD will add it in. Check an analysis (file added) by Mcafee on installation of it in the link.
  Ken   (further information)
Had problems for two weeks after installing ConvertXtoDVD, had to do system restore twice, still not sure if that fixed everything. Pcoufin is DANGEROUS.
Came with DVDfab. On Vista Ultimate x86 and x64 locks LG GGW-H20L Blu-Ray Drive completely. Remove and you are golden. Tested on nVidia and Intel chipsets.
Installs with VSO-burning engine (which may install with DVDFab)
  Muntra   (further information)
Used for 1 Click DVD
this is an access layer used in programs needing dvd/cd drive access, ConvertXtoDVD, DVD Fab, PhotoDvd, et Cetera, NOT A RISK
  JDuran   (further information)
When it was installing, it just froze there, so I don't know what it does.
Installed with prorams such as DVD Fab. It is completly harmless.
  John Appleseed  
I'm sure it is installed with 1Click DVD Copy
ConvertXtodvd installs this driver
It want to install itselfs during clone DVD 4 install. My windows ultimate 7 requires a valid digital signature, and won't let it install it. Just to let you know. Need to google for more info.
This file is bad news for vista after 3 factory recoverys on my laptop i finally found out it was this file making my boot time 15 minutes and it would take 10 minutes for anything on my desktop to open.Install convertx to dvd at your own risk.
it come i thin with a lot of ilegal programs like "dvd fab" and it allow you to clone a dvd...or something like this..any way was something about cd-dvd of your laptop..may matshita old driver error
downloads w/ ConvertX or some such thing. But why does this converter need to usurp my keyboard drivers?????? I had to uninstall b/c it would cause my laptop keyboard to malfunction i.e. one by one the keys would stop working.
it has something todo with dvd burning/decoding. If Pcouffin error showa up, open divice manager and disable it
Installs when VSO ConvertXtoDVD is installed
  Someone Who Knows  
its reponsible for burning CD/CDRW/DVD. My WinVista HomePremium SP2 can't load it because its not registered. Can't burn CD/CD-RW
It comes with a dvd decoder i.e power dvd etc,dnt think its harmful
Installed with DvdFab
I tested Ideal DVD Copy a few times. I'm in the habit of looking into "My Computer" program setup folders for each program I install. The first couple of times I installed Ideal DVD Copy, the patin couffin driver was not amongst its driver list. The third time it was. It wasn't until I had to do a restore to reset my PC that I found out the patin couffin driver would'nt allow me to do so. What it does for all dvd copy software is the same thing. Why, because when you have to do a restore to reset your defaults, it also resets your trial period for the dvd copy program, and you can continue using the trial program beyond its trial period if you continually restore your PC each time you use the trial program. That's why DVD Copy developers installed the Patin Couffin (VSO) software. If you don't believe me, install Patin Couffin and try to restore your PC to an earlier date. I have XP and my main drive was C:, but when I try to use restore, it tells me that it couldn't restore E:. And now my only choice is to format my drive again.

Best practices for resolving pcouffin issues

A clean and tidy computer is the key requirement for avoiding problems with pcouffin. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the pcouffin.sys process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
