I have asked this question before, with no response, When trying to play video clips from www.cnn.com, I get the error message Totem could not play mms are there codecs somewhere to upgrade Totem? What about Mplayer? I have no idea how to try to use Mplayer rather than Totem in Firefox,- the option to change doesnt seem to be in preferences anywhere... Is it possible to change and would it help? -- Reg.Clemens reg@xxxxxxx
