WWW streaming ogg video problems

I am trying to display a ogg video stream as a texture on an object using WWW. When I use an ogv file (file://path/myfile.ogv), everything works fine. When I use a video stream (http://mycomputer:8080), isDone is never true, isReadyToPlay is never true and yield return on the object never returns although the video will play fine most of the time if I go ahead and just use it without the checks. Sometimes though it will cause the editor (or the build) to just crash. Why doesn’t it work with a stream? coroutine code:

IEnumerator StartVideo()  
	{  
			wwwData = new WWW(sourceString);  

	//		yield return wwwData; - this will hang
			yield return new WaitForSeconds(3.0f); // using instead

	//		yield return wwwData; - this will hang
	//		while (!wwwData.isDone) -- this will never complete
	//	{
	//		yield return new WaitForSeconds(1.0f);
	//	}
			if (wwwData != null)
			{
				movieObj = wwwData.movie;
				string error = wwwData.error;
				if (string.IsNullOrEmpty(error))
				{	
	//				while (!movieObj.isReadyToPlay) - never completes
	//				{
	//					yield return new WaitForSeconds(1.0f);
	//				}
					renderer.material.mainTexture = movieObj;
					movieObj.Play();
				}
			}
	}

isDone does not become true if it’s not done and with stream it’s never done. So the behaviour that you’re describing makes sense.
