Provide a description that is worded well enough to be understood

A major part of the site Digital Concert Hall is concert videos which yt-dlp handles just fine. But when I try to download videos here, e.g. this one which lasts 44 minutes (can be played with the login credentials --username deydihurdo@gufum.com --password 3PXx-5.NDNmMD2! which you can use), it only downloads the trailer which lasts 39 seconds. Using build from commit ecfe479.

Provide verbose output that clearly demonstrates the problem

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
• If using API, add 'verbose': True to YoutubeDL params instead
• Copy the WHOLE output (starting with [debug] Command-line config) and insert it below

Only /concert URLs were ever implemented. cc @teridon

Interviews/films? Boring! You're right, I never even considered implementing this.

I don't think the discussion of whether the content I'm trying to download is boring or not is necessary. Also it's not like yt-dlp cannot download interviews. It can.
