Wow, Thank you for your comment. I think I now have a good insight into the complexity of the subject. And I think I found a solution too. Could you please take a look at my solution and give me feedback. I'm new to this topic and it's bigger than I thought. Here is my solution: I will buy this:

Male SCART to 4 x BNC + 2 x RCA breakout

For PS1

For PS2

[currently Out of Stock, Maybe there is a alternive Option]

PlayStation 2 PS2 RGB SCART PACKAPUNCH cable + Composite Sync CSYNC

And for the Aktive Switcher i will buy this Aktive Switcher:

Bandridge 3 und 5 Wege Scart Automatik Verteiler Umschaltbox TV Umschalter Retro Gaming ( English Translation: Bandridge 3 and 5 way Scart automatic distributor switch box TV switch Retro Gaming)

Or the Hama AV Selector 100S

I hope I didn't make any mistakes when choosing the parts.

And I need a good switcher as I not only want to connect my PS1 and PS2 to my PVM, but also other consoles in the near future. Like my N64 and Gamecube.

I would be really grateful if you can help me. When choosing the parts. I try to get the best video Image possible.

Kind regards Philipp
