Playing a movie with mplayer I noticed this error on the screen. The bits inside the ** .. ** are what bothers me (I added the **). I have an SSE capable cpu - why isn't it being used? What does the "unable to get.." bit refer to?

Opening audio decoder: [liba52] AC3 decoding with liba52
** liba52: unable to get 16 byte aligned memory disabling usage of SSE instructions **
No accelerated IMDCT transform found
AC3: 5.1 (3f+2r+lfe)  48000 Hz  384.0 kbit/s
Using MMX optimized resampler
Ahh - damn it - I found the answer - I was using a mplayer build with cpu detection. This seemes to switch off sse usage. i changed to a mplayer build made with p3/p4 optimisations, and the error went away.

<uhh we can't delete our posts can we..?>

No. Let it there for future reference if others have the same problem.
