MPlayer - GMPlayer Loaded but Not Working

I installed libsmbclient.so.0 and then ran apt-install MPlayer-suite 56.1MB later ... it appears to have loaded fully. I ran gmplayer and pasted http://www.christiannetcast.com/listen?station=ktkz-am into the URL window. It says it cannot resolve it. That address is from http://www.ktkz.com/ when I right-click on "Click Here To LISTEN LIVE" I tried pasting in http://random.chem.psu.edu/random.mpg and received an error about unable to resolve the address. Then I tried adding some mov files to the playlist but then cannot find them. I am also getting an Error 11 and gmplayer crashes. Anyone seeing this same behavior? Thanks! dmc
