Hi Neil,

Sorry, it obviously doesn't apply nicely to 0.26.

Try this one: http://pastebin.com/7WvXzg24

Apart from this, it might be worth trying a different video profile to 
see if that makes any difference.  I usually use VDPAU but occasionally 
I find OpenGL gives different results.  It's at least worth checking 
just to make sure that any playback issues are not related to that.

Richard.
