PotPlayer - play video as black and white (gray scale)?

[Ayaa]

Recently I needed to play some colorfull videos in black and white mode.
It is possible directly in PotPlayer?

Or some simple AVS command is needed? Thanks.

You can change saturation to zero . Push and hold Y key

I got this far:

In PotPlayer:

Preferences
-> Filter Control
-> Video Decoder
-> Built-in Video Codec/DXVA Settings
-> Use DXVA
-> Checked
-> DXVA2 Copy-Back
-> Select D311 with the GPU
-> Avisynth
-> Enable AviSynth processing
-> Checked
-> Add "potplayer_source()"
-> Checked
-> Leave other checkboxes on default
-> Load Script
-> Select or copy the avs script below

Then I set only this simple AVS script:
greyscale()


So, do I get different results if I use some 'text' parameter in this function (http://avisynth.nl/index.php/GreyScale) ?
I need help hoe to get it work with those "Rec???" parameters. Thanks
