Hi,
my first post.
First I got to say that Kdenlive is the best Nonlinear Editing Softwarepackage I found for Linux. Thumbs up!
It has many teething problems, yet thought. Ok, but I am confident of this program will get past that phase.
My problem is the following:
Its like Kdenlive can't acces the libmp3lame library. In the renderwindow when i choose mpeg-4 or flash it tells me
"unsupported audio codec: libmp3lame"
Also I can't render to XVid -> "unsupported video codec: libxvid"
And h2.64 is going to tell me -> "unsupported video codec: libx264"
I checked and I got all the asked for libs installed. I tryed to reinstall them... No improvement.
I am working on Ubuntu Maverick Meerkat.
Thx for your replies!

Just solved the problem for my own.
I ran the configuration wizzard once more and it detected the missing librarys :)
