The only method I've had any real luck with was using VLC to stream and to save the stream to a file.

In the browser I look at the network traffic in the developer tools and filter on "mpd" which gives me the link to the manifest. I go to VLC, select network stream as a source, paste in the URL to the manifest and then step through the screens to save the stream to a file. This works 90% of the time. Sometimes there is a stream that cuts out too quickly and once lately I noticed that the name of a playlist started with "drm". VLC could not even stream that.

I have to use a nightly build of VLC 3. VLC 2.x does not work. I have to go into the preferences, search for "dash" and select "fixed bandwidth" and put in the preferred height and width. Note that if you switch between VLC 2 and 3 you have to reset those preferences.

Hope that helps someone. Spent a lot of time figuring that out. I played around with the GPAC stuff with much luck.
