Embedded medai pkayer in a popup window

Hi,

I had created an embedded player in a pop-up window.
The player plays m3U files (since it must be streamed).
When clicking on the link in the caller page, the pop-up window opens, the player is shown, it buffers and then stops without actually playing the audio file.
The calling page is: neeman.sadot-irrigation.com/Listen.html
Sorry, I'm new here and can't insert URLs :-(
It is in Hebrew, but any link on the left side column will activate the pop-up opening.
Any idea, I'm quite lost here.

Hagay
