your wisdom

Guys, I really need you guys to share your wisdom with me right now. As you might know, I'm busy dld'ing prison break season 1 and well, I can't exactly play episode 19. All the others seem to work fine. So I thought: maybe it is the file's fault. So i downloaded another one, and another one, and another one. Non of them seem to work. This means, that it is probably my computer or something. I tried the divx codec pack, but that didn't do much neither. I tried the k-lite mega codec pack and that also didn't do much. SOOOOO, my question is: Do you know what i have to do so I can watch it!?

EDIT: my vlc plays like 4 seconds without viewing any video/audio
