The version you're using is very old. Update.

Ahh, thank you!

I updated to 18.10.0.9144 ... and now it works just fine!

Wonderful!

The second one seems to use something that is not supported yet by the internal code. You can set "mpv+youtube-dl" in preferences -> network and it will play.

This is strange! ... with "mpv+youtube-dl" both videos don't play here!

With "youtube" or "automatic" the first one plays while the second does not.

Be sure to have a recent version of youtube-dl.

You can also try to disable the option "use adaptative streams".

Thank you!
That was funny, because I had no version of youtube-dl installed at all!
I didn't know, that this step was required.

Now it streams both of them just fine!


One last question ... if I may?

The video seems to buffer 4 min ahead, which I'd like to reduce to 10 sec.

But more importantly: it just keeps the last 4 min in its memory, so if I want to watch the video again, after its finished ... it repeats the whole download again. So in short: can I increase the memorized chunk to the full length, just like the native youtube-web-player does?

I don't know. mpv has several options to control the cache. Maybe you can find something useful for you:
