  1. Hello everyone, I am new to Loadermax, and I recently started working on a new project that has multiple videos that need to be played on different pages, but at the same time keeping the videos in the background buffering so they can be played easily without waiting for them to buffer. For example, I have 3 pages, on page 1, page 2 and page 3, each individual page will have a different video coming from the same XML file. Right now I have all the videos playing in the same swf and they play as a playlist. here is the code. Any guidance on how to get this working would be greatly appreciated. This is also the link to the video player http://outermedia.ca/videoplayer/godaddy/ XML: <?xml version="1.0" encoding="iso-8859-1"?> <videoList> <LoaderMax name="videoListLoader" load="false" maxConnections="1" prependURLs="http://outermedia.ca/"> <VideoLoader name="videoID0" url="videoplayer/INTRO-1.flv" height ="406" width="720" scaleMode="proportionalInside" centerRegistration="true" alpha="0" autoPlay="false" /> <VideoLoader name="videoID1" url="videoplayer/DB02_C01_T01.flv" height ="406" width="720" scaleMode="proportionalInside" centerRegistration="true" alpha="0" autoPlay="false" /> <VideoLoader name="videoID2" url="videoplayer/DB03_C01_T02.flv" height ="406" width="720" scaleMode="proportionalInside" centerRegistration="true" alpha="0" autoPlay="false" /> <VideoLoader name="videoID3" url="videoplayer/DB_Animation_Ep 01_VBR2pass.flv" height ="406" width="720" scaleMode="proportionalInside" centerRegistration="true" alpha="0" autoPlay="false" /> </LoaderMax> </videoList> Main Class: package { import flash.display.MovieClip; import flash.events.Event; import flash.events.MouseEvent; import com.greensock.TweenMax; import com.greensock.events.LoaderEvent; import com.greensock.loading.LoaderMax; import com.greensock.loading.XMLLoader; import com.greensock.loading.VideoLoader; import flash.geom.Rectangle; public class Main extends MovieClip { //an array containing the VideoLoaders in the order they should be played private var _videos:Array; //keeps track of the VideoLoader that is currently playing private var _currentVideo:VideoLoader; //If true, the audio has been muted private var _silentMode:Boolean; //Check if we are in PlayAll Mode (true) private var smoothing : Boolean = true; //tracks whether or not the video was paused when the user moused-down on the scrubber.
