I think I recall that you can get it with GridFlow, but if ever you don't 
get it with the default decoder, there's another one that you can specify 
explicitly.

[#in stuff.mov] vs [#in quicktimehw stuff.mov]

or

"open stuff.mov" vs "open quicktimehw stuff.mov".

I think one of the two will work. But my actual experience is by decoding 
4-channel PNG videos... I just don't remember which way I did it, on which 
OS(es), etc.
