ra at linux:/cap/avfiles/avi> rpm -qa "ffmpeg"
ffmpeg-0.4.9-7.pm.svn20060924

mlt is compiled by ...
./configure --enable-gpl --avformat-cvs --enable-motion-est

... so configure print out this ...

ra at linux:/prog/cvs/mlt> ./configure --enable-gpl --avformat-cvs 
--enable-motion-est

but using ...

... don'T change the situation ...
Wrong syntax ?
I'm just a bit confused .....

... hhmmm, ok at least I have a playable file (also import into kdenlive 
works) with .mp3 extension, but I'm not sure if this is a "real" mp3 file - 
so please enlighten me on this guys ;)

also, please call me if you need more info.
