Pls. look at the start of the thread for any other details that I
possibly .All the above worked just great for a huge mileage untill
the upgrade.

But it's not the mencoder encode that could not be played, no!

It's this reencode:

Here comes my question. Explanation first.

It's not ancient, but it is old. I always built MEncoder/MPlayer (and
libx264) from source tarballs
(http://www.mplayerhq.hu/MPlayer/releases/mplayer-export-snapshot.tar.bz2)

Of course, if I have to try that, I will. I am not lazy, not that
lazy. But I have other work and worries on my hands, and I prefer
Gentoo provided packages whenever possible: less work and worry
overhead...
So since it is in the FAQ of mkvtoolnix:
http://www.bunkus.org/videotools/mkvtoolnix/faq.html
that mplayer is listed under question:
"Why does audio or video not play anymore since v4.1.0 (e.g. MP3, AC3,
DTS audio tracks, h264 video tracks)"
my question is, if I try and install the latest mplayer snapshot, do I
get that "header removal compression" issue with mplayer solved or
not, i..e. have the mplayer developers solved that issue in the meantime?

Wow, this took me time finding out what was wrong, and why it couldn't
work..
I like MPlayer very much, it'll be a loss for Open Source if it isn't
developed with the rest of the Open Source programs... I hate the M$
and related philosophy based on profit and world's moronry, but I am
not a programmer... I can't help. God bless you!

(If you don't read from me in long months or years (well I hope it
won't be years), I'll probably be in jail. My neocommunist government
hates dissent, and they esp. hate the right-wingers, albeit very
moderate and I dare say humane like me. I'm all set up for jail
already. They only need political decisions to prosecute, and they've
sentenced me already, and to jail people, and they usually set people
with made-up evidence, they've done that a whole lot a times, it's
their regular way with dissenters. May God save my country!)
