So the problem is that I can't import .avi files into Sony Vegas (10. Pro, but it was the same with 9)
I can import .mov files though. (other)
What can be the problem?
what is missing from my computer? (Win7.32)
I COULD IMPORT .AVI BEFORE.-BUT AFTER I REINSTALLED WINDOWS, I COULDN'T

You just can't import them period, or you can't recognized the video/audio from it.. You're probably missing a codec.

BUT
don't tell me Klite and other shit.
those didn't work
thanks

I searched for solutions, none of them worked. But they told me not to install any codec packs
