Yikes.
To be honest it's a wonder you don't all manner of conflicts with that repo setup.
k3b-codecs is avail in Packman I just checked. Problem is you have all yout repo priorities in mess.
Try this from a su terminal:
Code:
zypper in Packman_Repository:k3b-codecs
If this doesn't work try the next one below.
Code:
zypper in Packman Repository:k3b-codecs
