:-D Don't hurt yourself Basemeant,
I found this quote from someone having similar difficulties to yours
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. ?
In fact this driver comes up in problem posts all over for Toshiba DVD burning.
If all of the these ideas haven't worked for you, it may be time to check for malware causes.
Look forward to your reply.
TTFN
