starship troopers on vista

Damnit...just got this sometimes fun average FPS game that came out in 2005 that i played on my old computer which is XP but now i got vista whiich is pure crap.Install the game i ran it menu works fine i cant see the game cutscenes and can only hear so i said ''hmm maybe its just the cutscenes'' so when the mission starts all i see is a gray retarded screen and when i move my mouse around it goes all over the place and the sounds are ok but the video is just a gray screen...as i said menus work fine but what the hell!?
Im not sure if its the compatibility or my graphics card.The game is made for XP but people say they can run it on their vista...So can you guys help me out?
