OK, after some 30 hours I found the bug:
Every time an audio stream starts, that uses ad_liba52.c, a buffer of about
12 kB will be allocated and never freed. This may affect ad_hwac3.c as well,
I didn't dive in. My presentation system still uses mplayer-0.90 so I fixed 
the bug there [free buffer "a52_samples" in uninit() and 4 other places]. 

In the current release 1.0RC2 many things related to this driver have changed 
and therefore the fix cannot be ported that easy. But the problem itself of 
never calling a52_decode_end() or a52_free() still exists.

Another memory leak in release 0.90 is a not freed stream instance while
the demuxer tries to find the best video codec. Again I fixed this in 
release 0.90 only - maybe this has been done in 1.0RC2, I didn't look.

What has to be done now with this problem?
