Ah, I see we have a fundamental philosophical difference here...

So when your AI flops over you just ignore it? Me, I'd get it fixed.

Absolutely. Erroneous information is almost always an indication of a
problem that needs to be fixed. Just ignoring it can cause real harm.

If I roll up to a fuel pump labelled "100LL" and Jet-A comes out I'd be
pretty upset. But you would just say, "Oh, I guess when they said 100LL
they *meant* Jet-A" and figure that makes it OK.

That's right.

I am complaining about both. I am complaining about the server as the
root cause of the problem, and about the media player causing a
significant number of people to think that there is no problem and
therefore making it that much less likely that the problem will be fixed.

The problem with the media player is not so much that it plays the
video, but that it does so without providing any indication that there
is a problem. If the player put up a warning message along the lines of
"The server says this is an MP4 file but in fact it is not. This
indicates a problem with the server's configuration. Please notify the
maintainer of this site," before playing the video I would have no
quarrel with it.

What the player is doing is masking (part of) a common-mode failure and
making it appear as if it is not a common-mode failure. IMO, being
complacent about that sort of thing is the first step on the road to
disaster.
