“These work in web browser included into tvs like samsung”

and

“I have not tried it in the browsers thats included into tvs tho”

Are contradictory statements.

Donkey Kong Country 2 will always be the pinnacle of 2D Platforming, though Yoshi’s Island comes in a close second place.

VLC if you just want to watch it, MakeMKV/Handbrake if you want to rip it to a file.

VLC does have the codecs included, you’re likely just not opening it properly.

Then why does the link to download the client lead to the MS Store instead of Github?

Your client is still Windows Store exclusive? That’s a hard pass from me.
