multiple players

First, this works great for me tested on IE FFox, Chrome Safari Mac and PC and Android and iPhone. My one remaining question before I celebrate is this. Does multiple instances on a page degrade performance, in other words do all the players start buffering in the background or do players keep buffering after they are pause/stopped? It seems on multi-player pages the devices tend to slow down, especially on phones. But it could be something not related I am sure.
