Thanks Niels, indeed this helped me as well.
Now I'm getting a HUGE amount of "undefined reference to av_log"
It starts browsing the ffmpeg source tree (where I built ffmpeg) for libav c files
here's the one that makes it quit:
/usr/local/lib/libpostproc.a(postprocess.o): In function `pp_get_mode_by_name_and_quality':
/usr/src/ffmpeg/libpostproc/postprocess.c:758: undefined reference to `av_log'
/usr/src/ffmpeg/libpostproc/postprocess.c:776: undefined reference to `av_log'
/usr/src/ffmpeg/libpostproc/postprocess.c:787: undefined reference to `av_log'
/usr/src/ffmpeg/libpostproc/postprocess.c:899: undefined reference to `av_log'
/usr/src/ffmpeg/libpostproc/postprocess.c:901: undefined reference to `av_log'
more undefined references to `av_log' follow

You happen to know a way around this as well? Since you are using XUbuntu like I do you might
have experienced the same problem.
I don't hope it is getting any worse than that...
1. how many fixes in the code have been necessary until you (Niels) could run a save compile?
2. Could anyone point out what kind of developer libraries you installed in order to compile xine-lib savely?
I just added the minimum - meaning apt build dependencies for ffmpeg and xine-lib - this also covers all
of the libs listed in the sidux wiki (http://www.vdr-wiki.de/wiki/index.php/Sidux_VDR_DVB-S2#xine-lib)
