Just to be (less than) trendy, I did a google search for iptv players for Linux.
My daily driver is a LInux MInt 19.3 machine, which is a fork of Ubuntu.
The option that seemed best to me was Smarters, which I installed and have been using for today’s viewing (AKA: wasting time).
It works very well! And my machine is nowhere near modern.
It does have an old AMD video card and a dedicated card does help matters.
I’m going to try Kodi for this. Using Kodi on a stick or box doesn’t make much sense to me,
but on a computer, it might particularly for recording purposes.
Here’s where I DL’d the app:
