>             Project: Apache Flex
>          Issue Type: Bug
>          Components: mx: Video
>    Affects Versions: Adobe Flex SDK 3.4 (Release)
>         Environment: Affected OS(s): Mac
> Browser: Firefox 3.x
> Language Found: English
>            Reporter: Adobe JIRA

> Steps to reproduce:
> 1. Create an instance of the mx:VideoDisplay
> 2. Set the source to an flv and allow it to start downloading
> 3. Call the videoDisplay.close() method to stop the flv from downloading
>  
>  Actual Results:
>  - throws an RTE everytime
> TypeError: Error #1009: Cannot access a property or method of a null object reference.

> 	at flash.utils::Timer/_timerDispatch()
> 	at flash.utils::Timer/tick()
> This is the source where the RTE is coming from

> 		return;
> 	if (ns.bytesTotal >= 0 && ns.bytesLoaded != _priorBytesLoaded)
> 		dispatchEvent(new ProgressEvent(ProgressEvent.PROGRESS, false, false,
> 							 ns.bytesLoaded, ns.bytesTotal));
>

> 		 ns.bytesLoaded == ns.bytesTotal)
> 	   updateProgressTimer.reset();
> 	   
> 	_priorBytesLoaded = ns.bytesLoaded; // this seems to be the offending line
> }
>  
>  Expected Results:
>  video should just stop downloading without error
>  
>  Workaround (if any):
>  no possible work arounds. I have tried adding try/catches around the close, but because the doUpdateProgress is called from a Timer it doesn't catch the error.
