Watch Japanese television in mpv or vlc

https://tver.jp/
Run mpv on any /episodes/ url like this https://tver.jp/episodes/epz5ohem6r
Episodes are available for just a few days. If you find one you want to keep, download it with yt-dlp.

Use mpv's --no-initial-audio-sync option if you get an error about incorrect timestamps while opening a mov3 stream.

Sometimes my ISP messes with the DNS caching of youtube stream servers or something and I end up getting choppy playback with long pauses on the WNL stream. The errors look like this:
[ffmpeg] tls: Error in the pull function.
[ffmpeg] tls: IO error: Connection reset by peer
(Buffering) AV: 01:55:25 / 01:55:26 (100%) A-V: -0.000 Cache: 0.0s
[ffmpeg] https: Cannot reuse HTTP connection for different host: rr2---sn-p5qddn7r.googlevideo.com:-1 != rr1---sn-p5qlsn7s.googlevideo.com/...

Fix: run mpv with this option: --script-opts=ytdl_hook-use_manifests=yes. Not a single error message appears with this option. The mpv man-page says this option is set to "no" by default for performance reasons, but in this case, it's necessary.
