that's good.

no priority means lowest priority (ie 99 I think).

So, EPEL for example has higher priority than repoforge...

$ locate libmodplug.so
$ rpm -q libmodplug

So, as I suggested in my first reply you have a conflict between repos: 
you installed libmodplug from EPEL, it's the wrong version of the lib 
for the RF vlc, and it's newer than the RF version so it's preventing 
you from installing that correct version.

Solution 1: remove your current libmodplug, see what it pulls down as 
deps, then make the RF priority better (smaller) than epel and try to 
yum install vlc along with the other stuff that got removed when you 
removed the epel libmodplug...
Solution 2: use a VLC from another repo that likes the epel version of 

Bottom line: be careful when mixing several 3rd party repos, 
particularly if they are large multi-purpose repos like RF, epel, AT...
