[CentOS] Why shouldn't I expect more of CentOS/Linux?

Without the Dag repository, I get this error:
Error: Missing Dependency: libMagick-5.5.6-Q16.so.0 is needed by package 
transcode
Error: Missing Dependency: libpbm.so.9 is needed by package subtitleripper
Error: Missing Dependency: libppm.so.9 is needed by package subtitleripper

Without the freshrpms repository, I get the same error as I did before, 
where transcode conflicts.

Anything else I can try?
