I am running Ubuntu 19.10 as the only OS on my laptop. Up until recently, that is a few days ago, I regularly watched ITVHub in the Chrome browser on my laptop.
Yesterday I tried to watch a programme only to get the warning that I needed to enable "Protected Content" in Chrome or "Digital Right Management (DRM) Content" in Firefox. I tried to stream the programme in Firefox but got the same warning. I checked and the options were enabled in the Chrome and Firefox browsers. I can stream the BBC iPlayer and All4, two other UK streaming sites without any problem.
I then tried streaming ITVHub using Chrome in my Android tablet and it worked perfectly.
I regularly update my Ubuntu OS and there was an update prior to this problem occuring. Because Chrome can stream ITVHub on my Android tablet but not on my Ubuntu laptop I suspect the problem may be an OS problem.
I have all of the ubuntu-restricted-extras etc installed and the ITVHub was working on my 19.10 OS until very recently.
Any ideas of what may be causing this?
