Yes, I saw that warning... in the section on epel. There's also a
general 'mea non culpa' on that page about using 3d party repos in
general. For that matter, I'm pretty sure that there's a "we don't
guarantee" clause packaged somewhere in every linux distro. I even got
that line at work from paid-for redhat support in regard to a paid-for
redhat system. If I stopped doing things that "might not work", I'd be
fastened to the couch with cobwebs. I tried several of packages from
epel and they worked-- at least I haven't traced any specific problem
back to epel... well, until now... with your help. Point is, I don't
feel much tech shame for getting a package from epel. I figure that if
it was a terrible repo, it would say so in the centos wiki... or epel
wouldn't be listed there at all.

Right, and that's what was bugging me from the start: I had
libdvdread.0.4 installed and gstreamer-plugins-ugly wanted a *lower*
version. Aren't all the capabilities/functions from the 0.3 version in
v.0.4? My hunch was that, yes, they would all be there. This is basic
upward compatibility, a part of what linux has been about for decades.
If I had the time, I'd compare the two libdvdread library files to find
out for sure. The point of it would be to find out why the
gstreamer-plugins-ugly rpm complains about the newer libdvdread version.
To my mind, that simply shouldn't happen... might be an error in the
way it was packaged.

Yes!! That works... at least to get both of those packages installed at
the same time. However, totem is still broke; i.e., it's still telling
me that I'm missing a plug-in when I try to play a movie (mpeg-1 or wmv).
Hmmm. I didn't mention this previously for the sake of simplicity, but
few hours ago I did have both libdvdread.0.4 and gstreamer-plugins-ugly
installed at the same time and was able to play a movie (mpeg-1) in
totem. But "yum update" complained about it, so I figured I should fix
it. :( If anyone from redhat or someone packaging gstreamer should be
reading here, this might be a direction to look into.
Thanks again, Nicolas. You did help, but I guess totem needs more than
you and I together can give it.
