Selection wheels lag when using themes with videos

[Pieter Hulshoff]

And how should I go about doing this? I'm still not used to editing the layout.xml files   

Since RetroFE waits until all onHighlightExit animations are complete, just add something like this
-----
            <set duration=".25">
                <animate type="nop"/>
            </set>
-----
to any onHighlightExit animation. Change the duration to fit your preferences.
