Loading IP's from XML, load balancing and failover

[jiescobar]

Hello Everybody the code that I'm working on I guess I can say is almost there but not quite. I have an xml file that contains the ip values (2) to our servers, what I want to accomplish is: 1st read the xml and grab those values, 2nd randomly select one of those ip's and create the rtmp://...path to play the video, 3rd if one of those servers is down then use the other one to play the video and 4th if all servers are down display some sort of message to try again later. I am reading the xml and grabbing those values, I am randomly selecting an ip and creating the rtmp://...path, but where I am having problems is playing the video from the other server. What's happening is that when it hits the box that is down and swithes to the other box it actually show the first frame of the video but it doesn't play. Here is my code in my .as file:

package

I wanted to upload my FLA file but the system wouldn't let me, too big.
