## Verbose log

Since I currently do not have access to a Zattoo premium account (and the `zattoo` information extractor has not changed since the fork), I just mention the corresponding issues on `youtube-dl` project:
* https://github.com/ytdl-org/youtube-dl/issues/28535
* https://github.com/ytdl-org/youtube-dl/issues/22258

<!--
Provide the complete verbose output of yt-dlp that clearly demonstrates the problem.
Add the `-v` flag to your command line you run yt-dlp with (`yt-dlp -v <your command line>`), copy the WHOLE output and insert it below. It should look similar to this:
 [debug] System config: []
 [debug] User config: []

## Description

The `zattoo` information extractor is currently broken.
I'm the original author of that information extractor.
I already have submitted a PR to the `youtube-dl` project to fix that extractor (https://github.com/ytdl-org/youtube-dl/pull/28253), but it pretty much went unnoticed. I would like to contribute to `yt-dlp` and migrate this PR to this project. Since I currently do not have access to a Zattoo premium account, I cannot test it. So if anyone with a Zattoo premium account is interested to get the updated `zattoo` information extractor merged into this project, feel free to contact me (via email).
