Description

Tried some other playlists and they seem to be fine.

Assume this could be a formatting problem of the initial link. Opened that channel, navigated to playlists and took this link for that very same playlist wanted initially: https://www.youtube.com/watch?v=-gJaYKwreEc&list=PLF-k_OIEn_PMQ4bYJGD1Jx1OUAM7zwaEH It works. Please take a look and in case this is just a link formatting problem, just close this issue.

great find, looks like RDCM is prefix for a channel mix rather than video mix, UCGZ0LgTmAJn9Banetdr_ZFg and UCmvAV_za1KXGXSgC0o0v9DQ are the channel ids

I was looking at this code this morning. There is a weird situation where an error isn’t caught but it continues on as if everything is fine. Not sure what the story there is. Hopefully I can find some time today to look deeper.
