Another classic PC user here with a preference for XP SP2...and K-Meleon 75 Pro.
(For me, XP-SP3 and/or changing the kernel for Goanna are undesirable options.)
So=> Some videos play - and some don't.
Ran across mention of the Open H.264
codec just lately and that it is included in FF, but see no way to get it or install it...wondering if that or something like it may be made somehow to work in KM with my existing system ??
Aside of the above curiosity - browsed all around here looking for what may work for folks like myself and collected some tidbits - which became too messy for me to quote for attribution after a while - but all the same, my sincerest thanks to those who originally posted all this possibly helpful & useful info:

J.G. posted the following - but maybe only for Goanna & not OK for KM 75 ??:

Useful tools for testing:
Possible alternative browsers...
TheWorld Browser - looks to have stopped in 2010:
Iceweasel with libportable
KM is mentioned as a good alternative almost everywhere when the subject is brought up, BTW.
Here is a write-up that makes all my points about chrome despite how it seems written to favour it - just look at the extensive list of 'cons'!!:
Last ditch possibility if nothing else works for YT videos ??:
SMTube - YouTube browser for SMPlayer
There. That is all I have for now, and I will keep looking for good solutions...
That is - until such time as all options within my preferred reach actually do run out.
Of course by then I will likely be OK with having to use XP even less - and Linux even more than I do now, and perhaps even have a better way to get Android onto the big screen as well.
Best Wishes to All !!
