Are you trying to do the same thing I want to do? I've been noodling around
with trying to get Laszlo to play streaming flv files, but so far have only
been able to get their audio streams to play, without any video displayed.
I think the reason you're not finding an __LZmovieClipRef is that they're
only created under certain circumstances, like the view having a resource or
background color, or containing other views. There's a method called
makeContainerResource that seems to make a __LZmovieClipRef, which I think
gets called when you dynamically set the resource or add sub-views. Setting
the background color of a view also creates its __LZmovieClipRef.
Here's a snippet from my latest attempt, for a top secret "SimCheney"
project I'm working on, big time. Don't leak the source or I'll blast you in
the face with a shotgun! (No actually, feel free to leak the source! Just
please let me know if you get it to work!)
It just plays the audio from the flv, but doesn't show the video. The
resource="gofuckyourself_res" causes the __LZmovieClipRef to be defined,
otherwise it's undefined, which causes warnings, but the audio plays anyway
for some reason.

Subject: [Laszlo-dev] getting at the moveClip of a view
So, I wanted to get at the movieClip of a view (prototyping something
before actually diving into the LFC), and I couldn't figure it out. I
swear I've done this before.
Simple test case:
<canvas>
<view id="v" oninit="Debug.write(this.__LZmovieClipRef)"/>
</canvas>
shows in the debugger:
WARNING: test.lzx:2: reference to undefined property '__LZmovieClipRef'
<undefined>
Adding width, height and bgcolor to the view didn't help. If I set
Debug.showInternalProperties = true, I see __LZbgRef:, but no
__LZmovieClipRef
What's up?
Thanks,
Sarah
