Need help updating the driver on my video card!?

i was trying to play a DVD on my laptop, and it recently crashed so i had to reinstall XP, and i keep getting this message...



"Windows Media Player cannot play this DVD because there is a problem with digital copy protection between your DVD drive, decoder, and video card. Try installing an updated driver for your video card."



i downloaded a program to auto update it but its still not working... i have this video card...



Mobile Intel(R) 915GM/GMS,910GML Express Chipset Family (Intel(R) 915GM/GMS,910GML Express Chipset)



if someone could link me to a site where i could update it or any other help would be appreciated!|||sorry but not all dvd can be played on windows media player. you will need a 3rd party software to play the dvd. ex: intervideo, ulead dvd, etc.
