To achieve what?? All that is required of an AV cable is to carry picture + sound. Nothing else. This is change for change's sake. I don't recall scart getting an update every five minutes making devices incompatible with each other. As far as I am concerned if you plug in an AV cable it should just work, whichever "version" it is. There is absolutely no reason why it shouldn't. And £60 is a ridiculous amount of money to have to spend to get it to.
Well not quite….an ‘AV cable’ nowadays does much more than that! You have eARC, HDCP and CEC compatability plus the need for high bandwidth transmission which wasn’t needed just a few years ago.
Scart was an analogue connection….the world long moved on from that…perhaps you should too.
Technology progresses at an alarming rate which we just have to accept and not resent….
I bet you are not still using Windows 95…..🤔
