Any method to open video in the same window?

I've got maybe trivial question, but

If you open Youtube-player on device and open any video, it would be opened in the same window(or it looks like it's in the same window). Then you press 'back' it's return back to the previous state.

But when i try to open video in my program with
[CODE]this.controller.serviceRequest("palm://com.palm.applicationManager", {
method: "open",
parameters: {
id: 'com.palm.app.videoplayer',
params: {
target: //*My url*
}
}[/CODE]
It opens video in new window and it's necessary to close it after finish. And 'back' doesn't return me back to previous state.

It there any ability to fix it? I want the behavior will be the same as in youtube-player
