Threading issue Help Please

[Rattlerr]

I'v put in a Media Player that i made into my current project and working on using the System.Threading;

My First time really applying the Threading so i need some help with assigning a toolStripButton for the MediaPlayer using Threading and BackgroundWorker this is what i have so far..

 
using System;
using System.Threading;
using System.Runtime;
// didnt put in all the Using..
namespace MediaViewer
{
using WMPLib;
using MediaPlayer;
public partial class Form1 : Form
{
private Thread MediaThread = null;
private BackgroundWorker BackgroundWorker1;
{
public Form1()
{
InitializeComponent();
}
private toolStripButton2_Click(object sender, EventArgs e)
{
MediaThread = new Thread(new ThreadStart(this.RunMethod));
if (sender == toolStripButton2)
            {
                Application.Exit();
                if (MediaThread.IsAlive)
                    MediaThread.Abort();
                if (Thread.CurrentThread.IsAlive)
                    Thread.CurrentThread.Abort();
            }
}
private void RunMethod
{
Thread.CurrentThread.IsBackground.GetType();
            MediaThread.Start()

// this is where i want too MediaPlayer to run using the toolStripButton2_Click
while using the Thread & BackgroundWorker
}

So any help with this is greatly appreciated i always give out Reputation Points, My 1st time using Threading and BackgroundWorker
