 Sven Opitz | Device driver for sonic dvd burner |
 hearsjohnny | When I installed the latest version of Sonic's MYDVD I got an error message when I restarted stating that Elby Check has detected a corrupt Filter Driver PxHelp20! This driver will prevent your cd-roms from working properly . Remove corrupt driver from Registry? Yes No |
 Mark Peter van Sijll (NL) | Windows 2003 Server (All editions) will create a lot of Explorer.EXE and "Control Panel" errors |
| Greg Kanczes | I saw it on the system of a friend who had recently begun having problems with his system slowing down tremedously. I disabled it (along with other suspected services and drivers) and his system appeared to return to a normal operating state. |

| Urs Degen | Wird von NERO 6.xx verwendet |
 John | This file is the Sonic Solutions CD Burning Ripping engine used by Winamp 5. It's painful to remove, as it doesn't uninstall with Winamp 5. You need to manually remove it by deleting all pxhelp20 entries in the registry, including from inside the upper/lowerfilters for the CD devices. You might need to do this as it can cause incompatabilites with some IDE drivers. My Nforce 2 board with standard Microsoft IDE drivers just went into a boot/reboot loop because of phelp20.sys. It is possible to install Winamp 5 without the Sonic ripping module by deselecting it from the installation menus. |

 nodbruce | Slows CD drives drastically, causes fatal errors. |
| Szabó, Dávid | Caused crashing my (SIS645) IDE DRIVER, DMA doesn't work on my DVD-RW device, I don't exactly know, what this is. Probably the Sonic My DVD installed it. I haven't solved the problem yet. Good luck! |
| whit | had an incompatible driver with my computer and caused random reboots! a big pain and comes with sonic update manager |
| Ryan Goetzinger | It is a CD writing driver used by Sonic RecordNow. This software usually comes pre-installed on Dell PCs with CDRWs installed. Removing this file will break Sonic RecordNow. This DLL is also used by serveral other CD writing applications that have licensed the Sonic codebase to write CDs in their own applications. This file can get corrupted sometimes, resulting in bluescreens. If this occurs, delete the file, and re-install Sonic Recordnow. See also: Link |
| Ian Laurin | Answer-it is a networking problem. basically you uninstalled either of the 2 networking services (network load balancing or QoS Packet Scheduler). Don't think you need either on, but not having the elimates ip-address access to winsocket. long of it. "px" stands for pointer. "help" refers to windows/help and issue 20 deals with passport failure. the logic is a couple of years ago winsock only interfaced with tcp/ip and needing 2-way (seccure and non from hard ip not url) microsoft gave access to winsocket. as a result you need one of the two present (qos or net bal..) during boot for apps See also: Link |
| hidflect | not needed at all but insistantly keeps getting installed by rootkit exploit/trojan - it probably has some exploitable dual functionality |
| staas | is it possible to get rid of this without going in registry edit? my idiot admin disabled it and i really need to get rid of this thing. |
 burnt | Not dangerous, but I just got rid of that crap using this script: http://support.microsoft.com/default.aspx?scid=kb;en-us;320553 |
| Peter | Version 2.2.70.0 is installed by Adobe Photoshop Elements 3. Does not cause Problems here. |
| Y Pennog Coch | I just removed it manually (had to edit the registry), and now my CD drive works again |
| Shadowlight | Is used by some programs, but can cause some problems. |
| RobM | Part of a fresh WinXP SP2 Pro install, seems to be harmless. |

| jackal651 | This is also added by Nero. If the filter is removed, then you cannot burn to media (only burn an image to a Nero file) |
| Sonicshootdown | horrible sompletely screws up SPTI & ASPI. Cannont uninstall easily... DONT INSTALL DIVX6 it is bundled in it without asking if you want to install it |
| Jon Redwood | It is installed as a device driver for CD/RW and DVD burners. If removed the device will fail |
| Disliker of DivX installer | Divx 6 installs this as service but it doesnt show up in the services list. I got delsrv.exe from the windows 2000 resource kit and used it on pxhelp20.sys in the winnt/system32/drivers directory. |
| Tuba | On my system, it prevented the CD drives from working. Windows complained that the drivers for the devices could not be started. This site details the process of removing the problem. http://www.theeldergeek.com/restore_missing_cd_or_dvd_drive.htm See also: Link |
| Bernd Schultz | Verlangsamt das System. Hängt mit Nero zusammen. Nach dem löschen funktionierten CD-Laufwerke nicht mehr. Systemwiederherstellung war nötig. |
| johnm | Unable to get rid of it. Using WinXP 64bit. widows disables the PxHelp20.sys. Rated as incompatible. |
| P. A. Grifin | SEHR wichtig, ohne diesen treiber war mein laufwerk weg!! |
| dadslaptop | after removing some services via msconfig, my dvdram hldtstgsa4084n did not work at all. this file was not part of detailed drivers unitl i recovered my laptop. i guess it is needed to recognize cdrom somehow.any ideas? |
| TT | Einfach nur Nervig. Ich weiß nicht mit welcher Software er kam aber seit dem funktioniert mein DVD-Brenner nicht mehr. |
| Serg | After deleteing it I got problems with CD-ROMs - codes 19, 32, 39 |
| Jon L | Maybe legit, or maybe not. I do know that it caused Nero 5.5 and Nero 6.3 not to see my DVD burner, and also conflicted with Daemon Tools' sptd.sys, which caused my system to hang every boot. (Reinstalled Win2k before I worked out what the problem was, not happy at all that this junk somehow got on my system. Still no clue where it came from.) |
| Anton Jan | Required for Veritas' DVD Device Driver... |
| pop | CDrom drives |
| Michael T. | if you have any problems look for HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} for LowerFilter, delete data value, not the key! My cdrom drive did not work anymore after DEinstalling DIVX player in windows safe mode. install / reinstall in normal mode works fine |
| Luke | PxHelp20.sys comes with DivX codec/player |
| Rikki maan en | Added by Corel Photo album 6 |
| Lemon | Installed with Yahoo! Music Jukebox, probably to slow cd-rom ripping speed |
| RanuKanu | Virustotal.com found NO Virus in MY File, and it seems to belong to some Programm See also: Link |
| FP | Installed by PlexTools See also: Link |
| Gerry | PxHelp20.sys and Pfc.sys are installed by lots of different programs mostly multimedia type software. For instance along with the apps mentioned Mainconcepts Mainactor from Mediachance installes it. As has been mentioned it can be difficult to remove as you need to edit the registry in especial the upper/lowerfilters for the CD devices. |
| Avatar1165 | I just installed a new DVD burner that came bundled with Nero 6 software which installed this driver. therefore, I would assume that Nero 6 will not work if pxhelp20.sys is disabled, however, my computer runs much slower since this was installed. |
| James B | The Sonic Solutions cd-burning engine is also installed now with Google's Picassa photo viewer (which offers 'backup', or burn-to-cd capabilities). Windows Vista will also use Sonic's engine to power its built-in burning feature (see http://www.cdrinfo.com/Sections/News/Details.aspx?NewsId=18759). Windows defender (free, available from microsoft.com) will prompt you when this driver is installed on your system... in contrast, Picassa is 'recognized' software and is allowed to install. With Windows Defender installed, you can choose to deny this driver when an application installs it. |
| | shitdriver. lets my cdrom vanish. disabled via deleting filter entry in CurrentControlSet for CDROMS (MS has an article). kill it!!! |
| Calvin | It is a driver for CD and DVD rom drives. It's one of the worst ones out there but there's nothing to be concerned about, many CD writing software uses it. Do not get rid of it if it found its way on your computer, it's not a virus, it didnt get on there because you dont need it. Chances are you got it with software that requires it to work properly. |
| Huh | ok, this thing screws up your drivers. also, there is more files than pxhelp20.sys, some of those files says it was created the year 2003 on your computer, it also looks like it keeps making more and more files not sure about that though. but i know my computer cant read any disks and that happend 2 days after i got this file. This file can come from Winamp, so make sure you dont have the check box on positve at audio support files, Sonic Ripping/Burning Support. also, i think this file can cause c000021a, fatal logon error. it also disable files but how many and what kind of files i dont know |
| Huh | seems to be able to cause c000021a. logon procsess fatal error so you cant get your computer started. not 100% sure about this though, but since it starts during boot it could be very likely ? |
| 144 | It's DIVX 6.0 |
| RetupmocSOFT | Install Adobe Photoshop Lightroom 1.0, PxHelp20.sys will appeared in %SYSTEM%\system32\drivers |
| Henry J | after removing this driver you have to edit the registry to remove it from the CD/DVD driver (upper/lowerfilter) or else your drive will fail to work! (this driver is AFAIK no part of windows!) See also: Link |
| André Baron | Published by Sonic Solutions. Evil file, prevent either of my CD-ROM drives from working. Go through the registry and remove the lowerfilter entries for pxhelp20.sys to remove it. |
| Jim | Required in order to access my DVD/CD burner. |
| guest@ | Comes with Pinnacle Studio. Causes very bad things to my PX-760A DVD recorder + system instability + Errors and problems while burning disks from other applications + DVD+RW erase will never finish in Plextools |
| Dquixote | Suddenly appeared. PX engine device driver for XP. |
| Ralf Hermanns | is installed by winamp. Is not necessary when hearing music, maybe for cd ripping |
| Feuerblase | Installed by Sony SonicStage software |
| Tong Narak | PxHelp20.sys and Pfc.sys are installed by lots of different programs mostly multimedia type software. Mine got problem from added by "Corel Photo album 6". Shit! |
| ml | Prevents the Windows Complete PC Backup on Vista by blocking access to the DVD drive. |
| Vinod | No harm caused to Machine or DVD ROM or CD Writer (Combo Drive)... |
| Ben | This file caused my PC to not be able to see any CD/DVD Device, the only visible way to know that the device was there was in System Devices. The best option would be to delete Pxhel20.sys and all of its registry through regedit or some other means. After i did this, i was able to view and work my DVD-R Device. |

| SysAdmin1 | Made by sonic. Used by numerous apps as a cd/dvd burning API. Works with most systems but can cause device issues in some instances. If removed (through registry), software that used it will not be able to burn. |
| Sylvia Hayes | I had to rename it in order to install my Palm software, my DVD/CD player quit working but once Palm was installed I was able to enable it and get my DVD/CD player to work again. |
| YOP Dirty Dan | Apparently caused fatal stop errors in XP Pro when disc is loaded into drive to be read. If disc does load reading the disc by any program slows the computer. Next cd/dvd loaded will cause blue screen fatal errors in atapi or UDFS. Digital Signature was from Sonic. Used to be a faithful customer but their products have failed me tremdously. Link is to similar problem and solution. See also: Link |
| Stefan | You can uninstall it by looking for "PXEngine" in the HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall subkeys. You should see an uninstall string there, which you can use to uninstall. Beware though, uninstalling it breaks some CD burner software. |
| Paul Sanders | It breaks XP's (and hence VinylStudio's) CD burning functionality See also: Link |
| Andanator | Burning engine installed by Picasa2 |
| stefanop | after installing the DivX bundle my cd/dvd did not work anymore. I changed to empty string the key LowerFilter (that previously was "PxHelp20") and disabled / enabled the dvd in the device manager. now dvd is working. |
