German "smoking" == "tuxedo" :-)

A tremendous amount of MPEG4 variants has been in use for quite some time now (MS MPEG4, [Open]DivX, 3ivX, ...), and they all have been supported by mplayer as well as xine. Literally for years now...

You likely installed a custom build of OpenSSH at some point in time and now when you run 'ssh' it runs this outdated copy instead of Apple's copy. Outdated here means that it was built against OpenSSL 0.9.4something or 0.9.5something, not the 0.9.6b that is currently provided by Apple.

Run "which ssh" and see what it tells you. If it says "/usr/local/bin/ssh", you may want to remove that copy of ssh so that it uses Apple's version (/usr/bin/ssh).
