There are many tutorials out there but not so many for 6.4 and it seems people are having problems with running either Java 6 or 7 and Ant.

So does anyone know where to find a definitive guide? 

Should Java be version 6 or 7 and can I just `yum install java`? Then which version of `red5` should I be installing? On their site they have video tutorials that don't even reflect the sitemap of their site! 

so confused..
