problem with import a video clip ! need help.

Hi guys , i have a problem with importing a video clip in to my project , i tried several formats but with no chance (wmv, avi) , do i need a special video codec pack or … ! i have cubase 6 64bit with windows 7 ultimate 64bit. any help it would be appreciated .

Cubase from 5 on only supports quicktime format.
You can actually import some other formats but it won’t run properly.
