you can use different flvplayback skins (but their buttons are all about the same size). you can also create your own player with custom buttons but that will require more coding.
I've tried using different flvplayback skins and the playback buttons are all way too small. I tried following steps on how to use the Video UI Component but it doesn't seem to work. I added a "Play" button to the stage but didn't know what to name the instance of it and then how to do the Action Scripting for it. There were examples of Action Script and I tried the examples and they didn't work.
