          ns = new NetStream(nConnection);
          ns.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
          vidDisplay.attachNetStream(ns);
          ns.play(videoURL);
XML
<?xml version="1.0" encoding="utf-8"?>
<Playlist>
<Video Title="Chapter 1">media/video_1.flv</Video>
<Video Title="Chapter 2">media/video_2.flv</Video>
</Playlist>

Answer 1

everything should work as long as you wait for xml loading to complete before clicking your buttons.  you can disable those buttons when you app starts and enable them in processXML.
var videoURL:String;
var myXML:XML;
var myLoader:URLLoader = new URLLoader();
myLoader.load(new URLRequest("video_list.xml"));
myLoader.addEventListener(Event.COMPLETE, processXML);
function processXML(e:Event):void
button_1.enabled=true;
button_2.enabled=true;
          myXML = new XML(e.target.data);
          trace(myXML.Video[0]);
button_1.addEventListener(MouseEvent.CLICK, btn1Click);
button_2.addEventListener(MouseEvent.CLICK, btn2Click);
button_1.enabled=false;
button_2.enabled=false;
function btn1Click(e:MouseEvent):void
videoURL=myXML.Video[0];
          ns.play(myXML.Video[0]);
function btn2Click(e:MouseEvent):void
videoURL=myXML.Video[1];
          ns.play(myXML.Video[1]);
var nConnection:NetConnection = new NetConnection();
nConnection.connect(null);
var ns:NetStream = new NetStream(nConnection);
ns.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
var video:Video = new Video();
video.attachNetStream(ns);
addChild(video);
function netStatusHandler(event:NetStatusEvent):void { 
// you have no useful code here
play_btn.addEventListener(MouseEvent.CLICK, playClicked);
pause_btn.addEventListener(MouseEvent.CLICK, pauseClicked);
play_btn.visible = false;
var videoPaused:Boolean = false;
function playClicked(e:MouseEvent):void{
          if(!videoPaused)
                    ns.play(videoURL);
          else
                    ns.resume();
  play_btn.visible = false;
function pauseClicked(e:MouseEvent):void
          ns.pause();
  play_btn.visible = true;
          videoPaused = true;
