No video with supported format and MIME type found

[HoppaLong]

Googling about a problem can be a blessing or a curse. It's a curse when there
are thousands of listings (and possible solutions) for the same problem.

When I attempt to play a tube video a static image appears with this message:

"No video with supported format and MIME type found"

It could the browser, operating system, media player or a combination of two or
three. I tried different browsers. No change.

What can I do to resolve this problem?

I don't know about the others, but to get Otter to work with HTML5 videos on YouTube, I had to replace some files with those from the XP SP2 compatible version.
See here.
You can download otter-browser-xp2.zip from here.
Extract it to a temporary location, select all the files in the Program Files\Otter\lib\gstreamer-1.0 folder, and paste them into the same folder of your working version of Otter, overwriting if necessary.
I found that made YouTube videos work fine in Otter on XP.
I did it ages ago, and have never had to repeat the operation, even though Otter has been updated many times since then.
HTH.
