Maybe. Thanks for the input.

I've now looked in content.xml. The difference between getting the video 
in by drag and drop, and via the Insert menu seems to be purely that D&D 
links, while insert (by default) embeds the video. All other parameters 
seem the same:

<draw:frame draw:style-name="standard" draw:layer="layout" 
svg:width="34cm" svg:height="19.125cm" svg:x="17.6cm" svg:y="21.4cm">
<draw:plugin xlink:href="../../fireworks%20composite.mp4" 
xlink:type="simple" xlink:show="embed" xlink:actuate="onLoad" 
draw:mime-type="application/vnd.sun.star.media">
<draw:param draw:name="Loop" draw:value="false"/>
<draw:param draw:name="Mute" draw:value="false"/>
<draw:param draw:name="VolumeDB" draw:value="0"/>
</draw:plugin>
</draw:frame>

and

<draw:frame draw:style-name="standard" draw:layer="layout" 
svg:width="29.085cm" svg:height="16.36cm" svg:x="2.8cm" svg:y="2.2cm">
<draw:plugin xlink:href="Media/fireworks composite.mp4" 
xlink:type="simple" xlink:show="embed" xlink:actuate="onLoad" 
draw:mime-type="application/vnd.sun.star.media">
<draw:param draw:name="Loop" draw:value="false"/>
<draw:param draw:name="Mute" draw:value="false"/>
<draw:param draw:name="VolumeDB" draw:value="0"/>
</draw:plugin>
</draw:frame>


If I do an insert, and ask for the video to be linked, I again get the 
poor fade-in  behaviour - the dummy placeholder shows (behind the text) 
as the slide fades in and is replaced by the playing video (on top of 
the text) when fade-in is complete.

Doesn't seem affected by switching between nv and nouveau graphics drivers.

I've no idea yet where the z ordering is saved. In all cases the video 
plays in front of everything else. Might this be a video hardware 
limitation of some sort?
