This works great for one video, but when I call stopVideoPlayer to stop and load a new video, it plays the new video and sound but then it plays the sound from the previous video over the top. I am thinking that I need to delete / destroy the sound from my previous video before loading the new one but cannot figure out how to do it. Anyone got any ideas?
Thanks,
