Yes, there are many professional video edditing software packages and most
of them will install codecs and CDROM filters making conflicts with each
other. And so I have a second windows installation for them and install on
demand. On the other hand, having all of them together benefits that you can
do specific task with the application that does it best. Ulead alows me to
remux DVD compliand MPEG-2 files without recompression for quick authoring.

no such option

Here is what I found:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}]
LowerFilters=PxHelp20
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PxHelp20]
FILES:
C:\WINDOWS\inf\pxhelp20.inf
C:\WINDOWS\system32\drivers\pxhelp20.sys
I am testing this on backed up Virtual PC so fatal making mistakes is
considered safe
The .INF file is a good point to start from, becasue I can see how it was
installed and reverse it. I can also create a dummy write-protected .INF
file with the same name, before installing and this should block the entire
installation

No install script should mean no driver installed.
