Since Xojo 13.3 the .Rate Property of MoviePlayer has disappeared. Hence I used it quite regularely in different types of programmes I would like to know if someone knows an easy usable workaround.
(To all those mentioning “MonkeyBread” I have to confess that I find it rather difficult to find the concerning routines and if I found them, the explanation how to use it is doubledutch to me.)

You could download MBS Plugins, look into the examples for AVFoundation named “MoviePlayer Rate” and test whether it works for you. If nothing changed it should work fine for Mac and Windows.
