Thanks Johnny!

I went to elrepo because back when I originally went to C7, rpmfusion
did not have an EL7 repo. I kept checking back, occasionally, for
several years, and only recently learned that they now do.

So now I"m stuck with elrepo. yum gives me a huge list of things from
elrepo (a lot of them are things I certainly didn't install on purpose,
must have been brought in as dependencies I guess.)

I also was using the nux repo because he had some things nobody
else had. but when I discovered that some of the things I had gotten
from nux were way out of date, I checked rpmfusion and saw they had
modern versions and installed them. (xfreerdp, VLC)

I'll have to go carefully through all the stuff from nux and elrepo
to see if I can replace them all by using rpmfusion. If I think I
can I guess I need to (probably) painfully remove them all. I can
imagine dependency hell happening there though.

Thanks for the explanation.

Fred
