epel is not a bad repo, it's just mixing repos that causes problems. If 
you install unrelated packages from this and that repo you can be OK, 
but otherwise (eg if they're related through a dependancy as was the 
case here), you can run into problems.

if the soname version changed chances are it's not compatible ;-)
that's why shared libs are versioned.

well now that you have configured the rpmforge priority high, you should 
be able to yum install xine (or mplayer), so that it comes along with 
all its deps from rpmforge. Like Mark, I've always preferred them both 
over totem.
I know the rpmforge xine and mplayer install and work fine.
Although this will only work if you don't have other conflicting 
versions of packages already installed from eg epel or elsewhere. 
Otherwise you might have to remove those versions so they get pulled in 
from rpmforge, like you just did for libdvdread. This can get hairy if 
you've got tons of various packages coming from different repos.
