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.

Burning engine installed by Picasa2

It breaks XP's (and hence VinylStudio's) CD burning functionality

Mit pxhelp20.sys erkennt das DVD-Laufwerk LG GSA-H10N (Firmware JL12) von ihm selbst geschriebene DVDs (+R DL, Intenso, 8x) nicht mehr, ohne den Treiber jedoch einwandfrei. Ohne pxhelp20.sys arbeitet DivX nicht einwandfrei. Im Treiber ist kein Virus enthalten. Ungefährlich, aber sowohl förderlich als auch hemmend. Vielleicht kommt ein Update?

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.

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.

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.

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.

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.

No harm caused to Machine or DVD ROM or CD Writer (Combo Drive)...
