For YouTube, https://www.4kdownload.com/products/product-videodownloader .
For other stuff, https://software.charliemonroe.net/downie/ . (Yes, it costs money. Don't be cheap.)
If you need access to post-2016 footage, you can either root around on eurovision.de, or cough up a little more money and get a VPN.
I used the wonderful Mac app <strong>Downie</strong> to save the broadcasts for my personal archive, This app can download vod-streams and save live livestreams while they are being streamed.
With <strong>Fission</strong> (also a Mac app) you can extract and split the audio from videos without transcoding.
I saved the 1080p streams of these three shows with a nice little Mac app, meaning: no screen recording and transcoding of the video and audio, just the actual streams. Where's the best way to share these MP4 files? 5,33 GB total.
I highly recommend Downie. It's a sweet little app that will download any recognizable audio or video from almost every conceivable site you might be looking at with just a click. It's highly customizable. I've been a power user of it for a long time now.
Downie might be the app you're looking for. Not free but it has a free trial period. The developer is very responsive and is frequently updating and adding to the extensive list of supporting video sites.

About YouTube i have already reported the problem to the dev.

What's new?
UI Redesign – the UI has been redesigned with more options at hand, while not cluttering the UI.
Menu Bar Control – control the app from the menu bar – without the need for the Dock icon.
Customizations – custom postprocessing using your own shell script, custom file name formatting, and much more.
Improved Speed – YouTube videos load up to 6 times faster with Downie 4 when compared to Downie 3!
Metadata Improvements – the metadata that Downie gathers can be written into an external JSON file for further custom processing.
Improved User-Guided Extraction – the UGE window now has history, allows saving favorites and much more.
... and much more! - many minor improvements, like custom naming schemes, option to force MP4 downloads, better cancellation, priority flags, etc...
I've tried most of them, and none have been as successful at actually downloading content (from anywhere), had a better UI/UX, and more responsive developer support.
