Hello.
I just want to ask how to change default values of brightnes/ sturation, etc on HauppaugeHVR-1300 (analog part)?

I was able to change it by connectin graphstudio and setup one of the filter when LiveTV was ON in MP.
I lower brightnes becouse it is to bright compare to TV (using PIP mode to compare).

But after MP restart, values went back to previous setting (lookd like MP have some predefined values).

Any tips how to configure and store such settings correctly?
Thanks.
