If it's the same in another browser (easy to try), it's the site or your ISP or your connection with the ISP and there is nothing you can do about it.
If it's better in another browser (which I doubt) you've solved it.
YouTube videos work just fine. When I look at a movie trailer on - https://www.imdb.com/ - they also work just fine, although sometimes the video ‘stalls’, but its ‘never’ fuzzy / burry.
No other issues with desktop Dell Inspiron 3647 PC, windows 10. CPU under 15%, memory under 25%. Don’t have any ‘other’ tabs open at the time and not running any other programs at the time. 16GB ram. Intel Pentium CPU G3220 @3.00 GHz
Any suggestions on how to fix/improve video. Audio not an issue.
Thanks in advance
