Im having heaps of trouble with FCP studio 2

Ive installed it on an HP zd8000 notebook running ideneb 10.5.5
everything ELSE works a treat on the laptop

but firstly, when i installed (tried to install) FCP it told me i had 0mb of VRAM... which is untrue, i have 256mb of VRAM according to system information.

so i forced the install using pacifist and everything installed correctly to where it should

but when i try and run FCP/idvd/dvd studio pro i get an error message

"you cannot open this application because it is not supported on this architecture"

im a little lost as to where to go next, the FCP disks are legit, im not new to FCP or setting it up
but for the life of me i cant get this damn software to run!

anyone else run into the same problem? any solutions out there for me?

any help would be awesome <3

The problem is probaly your video card, you might want to flash the eeprom to a mac version. Also the video card has to support Quartz Extreme

how exactly would i do that ?
and would it affect the card if im dual booting vista and osx?

yeah it probably would affect your windows install
