Axel,

I've updated the packages but I still have the same issues:

Floating point exception

I came to the conclusion, that it may have to do how ffmpeg is being 
called by nuvexport.
When I'm converting a mpeg2 file "manually" it will work...

For your info that's what nuvexport does:

system call:
mkdir -m 0755 /tmp/fifodir_27887/

forking:
/bin/nice -n19 /usr/bin/mythtranscode --showprogress -p autodetect -c 1 
-s 2006-09-30-12-29-00 -f "/tmp/fifodir_27887/" 2>&1

forking:
/bin/nice -n19 ffmpeg -y -f s16le -ar 0 -ac 0 -i 
/tmp/fifodir_27887/audout -f rawvideo -pix_fmt yuv420p -s 720x576 
-aspect 1.33333333333333 -r 25.000 -i /tmp/fifodir_27887/vidout -aspect 
1.33333333333333 -r 25 -croptop    12 -cropright 14 -cropbottom 12 
-cropleft  14 -s 320x240  -vcodec mpeg4 -bit_rate '384' -title '1 SF1 -

'51' -max_qdiff '4' -qmin 31 -acodec aac -ar 48000 -async 1 -ab 64

Cheers, Walter
