Ok,heres the real answer, now most of the keys on a keyboard(all the letters, space, enter, control, numbers) won't do anything in your program unless you program them to do so. There are however certain combinations of keys that will exit you program such as alt-tab these are called system keys and can be disabled by using the command
disable system keys
and enabled by
enable system keys
so basically unless you program a key to skip your video clip the player/user won't be able to do so, but bare in mind most people won't want to see a video clip before they play, especially if they've seen it before!!!
