Hmm, interesting. If you rename the file to remove the
".mp4"
extension, and then run the "file" command, what does it report?
Technically, you may not even need to remove the .mp4 extension.
I wonder whether the file is:
- not actually an mp4, but just close enough to one to fool mplayer
into thinking it is (probably unlikely);
- or more likely, corrupted.
Can you re-download the video and check whether it is the same?
Not likely since Intel has proably cleaned house 5 year+ back, it is a
long since discontinued motherboard. Over a decade old now.
(Running diff on the old copy and the new will tell
you if there are
any differences.)
If you have a URL for the original, I'm willing to download it myself
and see if I can get it to play.
But your reference to using file on them gives odd results indeed!

So its no wonder at all why mplayer fails. I should rename them and see
if evince can render. Which it does flawlessly, about 130 pages of them.

Thank you very much. file has earned its keep.
