How to unlock all of the videos on monster jam the game?

ive almost unlocked every truck except for avenger and ive gotten first in every event help please|||i have monster jam for ps2. i also unlocked all the trucks by coming in 1st place in every single event and also hitting the target points. still no video. then i noticed the next point target was 550,000, so when i hit that point total, i unlocked 1 of the 4 videos! then i have no more point targets to hit and i' am lost now how to unlock the other 3 videos! well, at least i unlocked 1 video. no one has any cheat codes or advice. hope this helps... oh, and if you want to know how to build up your points, simply do donuts on the stadium racing to get a high point total of 5000 points then finish the race, it's okay if it takes you 10 minutes! once you come in first, it doesn't matter. same goes for all the racing, come in first, then go back and do a lot of donuts, crush everything, do wheelies whatever it takes to build your score, then finish the 3 laps in last place. that's how i built up my points!
