Review comment (suggestion):
I'd do this to maintain the old behavior
```suggestion
        video_id = traverse_obj(parse_qs(url), (('id', 'qid'), -1, {int_or_none}, {str_or_none}, any))
        if not video_id:
            raise UnsupportedError(url)
        webpage = self._download_webpage(
            update_url(url, netloc='mediaplayer.nobelprize.org'), video_id)
```
