can't import AVI type 1 to premiere CS6
the file codec is dvsd (DVC/DV Video)


Usually DirectX comes with a DirectShow DVSD decoder. But maybe this decoder has some issue with your file(s).
Could it be you've had at some time software by Pinnacle, Sony, MainConcept, etc on your old system installed, whose DVSD decoder could have been used by Premiere Pro instead?
