Rendering crashing and Codecs not supported

I have installed Kdenlive on Fedora 17 KDE and there are some issues with rendering files at the end.

When I render as mpeg-2 or mpeg-4, the video will render but then display the message:

Rendering of /mnt/data/Videos/KDEnlive/untitled3.mp4 crashed
[swscaler @ 0xb3443ee0] Warning: data is not aligned! This can lead to a speedloss

I can not even start rendering as avi because all the avi profiles say "Unsupported audio codec: pcm_s16le.

The mp4s play well in VLC, but there might still be issues with them I'm just not noticing right now.

Can anyone help me to get this fixed?

Small Update: I ran the configuration wizard again and now when trying to select avi, it says "no matching profiles" and there are indeed none in the list.
