Question: How can I find out if jPlayer is playing?
I tried this `alert($.jPlayer.event.playing);` but it doesn't work.

Answer: 
Kyle's method works fine, here's a fiddle to demonstrate it in action:

However, ordinarily you wouldn't need to access jPlayer's internals like this, being an event-driven plugin.. would it be cleaner to respond to one of jPlayer's many events (at the appropriate moment)?

```
var duration = $('#jquery_jplayer_1').data("jPlayer").status.currentTime;

if(duration){
  // Source is loaded and playing 
}

```
