In a perfect world doing IVTC would result in perfectly restored progressive frames. However, I've seen a whole lot of video that has been trashed by being telecined -- residual ghosting and all kinds of other stupid stuff.. So a lot of the time you still need to deinterlace IVTC'ed content to get the best frames possible.
