HD videos won't play on computer..?

I recored some stuff using an HD video recorder. I downloaded it onto my computer but now I can;t watch it. The players on my computer seem to be too slow - I can hear the video properly but I can't view it (it's either all black or in super slow motion.)
What can I do?
Thanks =)

I should add - it;s only videos taken with this hd camera - videos taken on my camera play fine...

you could always convert it into something else like
WMV or anything like that
I like the site zamzar.com
you can download videos or convert them
(plus, its really easy to use)
