How can I setup Mozilla to view video
 

I am running RH 9.0 and I want to be able to see movie previews & such on the web (like those at www.777film.com)

I need to get a quicktime or real player plugin (preferrably quicktime) anyone know where I cat get these for Linux?

Try:

You can also try mplayer.

Or you may use the mplayer plugin for Mozilla

Hope that helps...
