mplayer one last time :(

[Monah Baki]

Hi, sorry for being ignorant, but I don't want to switch to another OS if freebsd can do the job.

Based on the advices I installed the following on Freebsd 5.1:

multimedia/openquicktime
multimedia/mplayer
www/mplayer-plugin
www/mozilla (1.4)
www/mplayer-fonts

Still can't get mplayer working. I have all the required ports installed based on what the 
freebsd.com/ports website said, I can't think of anything else, I'm completely lost here.
