Oops, my mistake - kdenlive already uses "filename" as the attribute tag name. 
when calling render.

Does piave treat rendering a scenelist to a file in the same way as playing a 
scenelist to a video window? If that is the case, then it might be that we 
don't need a render command at all, but need an improved command for 
specifying the output device to use.

e.g. instead of calling "render" to render to a file, we do something like :

<addOutStream>
	<outstream>
		<file filename="">
			<container format="libdv" />
		</file>
	</outstream>
</addOutStream>

<play/>

And to play a file to screen, we do something like this :

<addOutStream>
	<outstream>
		<video type="xv"/>
	</outstream>
</addOutStream>

<play/>

How does this sound?

Cheers,
Jason
