Having just posted on the joomla forum, I've found this offical one - sorry guys, here's a copy of what I posted..

I'm using the excellant All Video Plugins with wmv files. Although the plugin works fine, by using a smaller video setting it shrinks my videos smaller than the control panel.

End result.. big panel, with a tiny video playing.

I think there's a parameter for it somewhere that auto-stretches the video to fit the size of the panel.
(could be.. autosize ??)

Is there a way of including this into the plugin_jw_allvideos.php file so it does this automatically for me ?

I have very little knowedge of php.. so any help you could give me would really help me out.
