Mplayer not playing streaming video

[david walcroft <david_walcroft@xxxxxxxxxxxx>]

Hi,
   As the header states,I get audio but not video in FC5.

Using "[david@reddwarf ~]$ rpm -q mplayerplug-in
        mplayerplug-in-3.25-1.fc5"

      [david@reddwarf ~]$ rpm -q mplayer
      mplayer-1.0-0.26.20060314.fc5

I think both rpm's listed are Freshrpms and should not conflict and I 
cannot tell if the correct codecs are being used.
