after upgrading to k3b 0.10.1 I wasnt able to burn an audio projekt from mp3 files. the erroro message was "unsupported format". K3b emerged without errors and i tried to remege it several times with only machr=i386 -O2 but that didnt change anything. After downgrading to 0.10.0 everything works fine.

Take a look at Settings -> Plugins and see if you have an audio decoder for mp3 (it should be there if you compiled against libmad (mad USE flag)). Can you play mp3s from k3b?
I didnt change my useflags from 10.0 > 10.1 and back to 10.0 again and yes i could play mp3 inside k3b.
Problem existed here, too - when I started k3b it told me it would not find some libs - it searched for them in /usr/lib - but actually they are in /usr/kde3.1/lib That means: for name in /usr/kde/3.1/lib/libk3b* ; do ln -s $name /usr/lib ; done fixes this. (actually i haven't digged deeper for the cause of this yet - there might be better fixes - but this one works fine)
0.10.2 is out now, you may want to check that.
The bug persist.
Even in 0.10.3.
the script: for name in /usr/kde/3.1/lib/libk3b* ; do ln -s $name /usr/lib ; done worked for me
please try a fresh k3b 0.11 installation
please test it with 0.11.1
solved with k3b 011 versions
I am seeing this issue with k3b-0.11.10 Others have reported this recently: http://forums.gentoo.org/viewtopic.php?t=166280&highlight=k3b+unsupported+format Other forums entries were along the lines of including the mad USE flag, but i have that anyway.
