halo game and video format

[dirtfarmer]

i think i may have made a error is get a game off e bay from UK
been do some reading, i now understand we use differnt video format

bid on the game HELO, and won, and it contract, so gluess i struck with
it, for better or worst
i never once thought of differnt video format, PAl stardard in UK and
we use NTSC in canada
now im unsure if it will work now

question is how many ver of helo are there?
would ther all work on any compter?????????
