It says "You have version 20,0,0,267 installed."

It says these have blue check mark
HTMLVideoElement WebM VP8 Media Source Extensions MSE & WebM VP9
It says these have red exclamation mark:
H.264 MSE & H.264
My browser says it has OpenH264 Video Codec provided by Cisco Systems, Inc. 1.5.3 - and is always active
There have been many times I get the same message. Funny thing. When I download the clip, it plays just fine in my players.

That is not used for multimedia playback. It's in Firefox for the Hello feature, for WebRTC use.
Overall, you really need to think about upgrading to Windows 7, at least. Or switch to a Linux operating system on an old PC. I would be surprised if Firefox support for WinXP continued to the end of 2016.
Windows XP doesn't include support for playing H.264 encoded MP4 videos, so you wont be able to use the HTML5 media player to see such videos.
You can set these prefs to false on the about:config page to disable the HTML5 media player to see if the website switches to a Flash based player.
- media.windows-media-foundation.enabled
- media.directshow.enabled
You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
