Nero MPEG-2 encoder plugin advice

[DLF]

Got the "Setup.exe" file for the Nero MPEG-2 encoder plugin and trying to find the switch(es) to install it silently in my RunOnceEx. I've run it with the...

/?
/help

...switches and it just wants to install - gives no advice. I've use the Universal Switchfinder executable and it reports "unknown installer".

I've got the "wma20933.exe" wma-plugin and that installs with the...

/SILENT /NOREBOOT

...switches faultlessly same as Nero itself. I've tried the MPEG-2 setup with this too and it just comes up with a dialogue box to "Install" - so no good.

Does anyone know the silent switches for the Nero MPEG-2.exe plugin?

Edit 5/15/05: Or can it be integrated into source and repacked?
