I'm not good c-scripter and haven't test this. Anyway, shouldn't it be something like:

Code:

---

var x;
function myst_movie1()
{ if (EVENT_TYPE == EVENT_IMPACT) {
msg_show("Congratulations, you've earned the right to see one of the 4 mystery videos.",10); //?
media_play("bleach.avi",null,100);
x = media_handle;
while(media_playing(x) != 0)
{wait(1);}
exit; //sys_exit("Game Over"); wait(1);
}}

---

Code:

---

action end_game
{
my.enable_impact = on;
my.event = myst_movie1;
}

---
