Description

Youtube-dl says that the playlist has 28 videos, but it has 30. Even if some videos are not available due to whatever reasons or the playlist contains duplicates, it should display the same number of videos as the browser does.

2 video are duplicated in this playlist.

@dstftw Yes, it has duplicates, it literally says in the issue:

Even if some videos are not available due to whatever reasons or the playlist contains duplicates, it should display the same number of videos as the browser does.

I explicitly want duplicates and want the same order that I get in the browser, what is the problem? And why have you deleted two comments? The comments were usefull and correct.

[sgfjsgfef1]

And the issue is perfectly valid.
