[I changed this from a reply to a thread, to a separate thread]
I have attached a document that explains how to set up Poodll with Red5.
I can not support you on this. And it is a bit difficult. And soon it will be difficult to use Flash at all.
If you can just use Poodll 3 with the tokyo.poodll.com server, and I think that is better. As HTML5 support gets better, you can forget about Red5 and Flash.
