Conflict with different version of same package

After changing several repositories I can’t make a complete update:

:~> sudo zypper dup
[sudo] password for root:

2 Problems:
Problem: 1: problem with the installed libdca0-0.0.7+2-10.8.x86_64
Problem: 2: problem with the installed libmpeg2-0-0.5.1-9.49.x86_64

Problem: 1: problem with the installed libdca0-0.0.7+2-10.8.x86_64
 Solution 1: install libdca0-0.0.7+2-1.7.x86_64 from vendor openSUSE
  replacing libdca0-0.0.7+2-10.8.x86_64 from vendor VideoLAN Project (http://www.videolan.org)
 Solution 2: keep obsolete libdca0-0.0.7+2-10.8.x86_64

Choose from above solutions by number or skip, retry or cancel [1/2/s/r/c/d/?] (c): 



One shouldn’t use the VLC repo additionally to the Packman repo. So solution 1 .
Remove the VLC repo afterwards.
