The streams are not the problem. Sometimes with content that was especially hard to find I'd grab the URL to the stream and download it via curl.
The problem is getting there. You have to navigate through treacherous sites with dubious "Stream now" buttons that bring even the best ad blockers to their limits. With myriad "sorry your stream is in another castle" and CAPTCHAS so complicated they could summon Cthulhu.
I think op doesn't want to navigate that shit with a remote keyboard and mouse and would rather have a nice interface that hides all that shit.
