Driver installation, grabby?

Who was on my last question probably knows how to go on…

and I bought a video grabber today. I want to connect the Wii to my laptop. I've already watched a few videos, but don't know how to go on anyway!

I will upload pictures here, which you may need to do something with to help me better.

In this picture you can see where my arrow is: HP webcam, but I want the video grabber to be there so that it can play the games on the Wii.

Here you can see what's up to now:

Try with OBS https://obsproject.com/de that is a current software that normally gets along with such grabbers. Such included software is just ancient but should still work.

If you only want to play and do not record anything, the VLC player should also do it

I just wanted to connect this to the Wii, is that also possible?
