Video codecs

In just moving over from Windows to Mac, some pieces of video i'd downloaded from the net won't play...

I've downloaded Divx & Xvid codecs, but not sure which other ones windows might have already downloaded or were part of media player before...

Does anybody have any ideas of things to try, until i'm covered?

Thanks

another divx codec you'll want is found at 3ivx.com, you also need a mpg 2 and mpg4 codecs, about 99$ each from apple, heres my quicktime folder that has my codices.o, is there a specific filetype you need to use? do you have quicktime pro?

That's fixed it... thanks
