You Tube Buffering Problem

Hi

I have problem with You Tube buffering.The whole application is run as given bellow-

1. My Activity is Start in which I create a server UDP socket which wait for data from client side

2.Then I go to Home page start web Browser and then Start any You Tube Video.

3. My background activity finds data send by Client and generate a Dialog window activity with "yes" and "No" button starts.

4. After clicking on any Button the dialog window is disappear.

Now my problem is when Dialog window appear the You Tube video is stop and Media Player is disappear and never resume even dialog box activity is stop.So how can I continue You tube video Buffering when dialog window disappear.
