Theoretically these can lose a small amount of vertical detail or confuse a subsequent deinterlace or IVTC function but so far in my own testing I have not found it to be a problem.  So if you intend to keep your video in interlaced form, certainly use these.  And if you are downsizing you may find that doing the <tt>InterlacedResize</tt> first before a more costly deinterlacing step can give you a small performance advantage on other material. But this is still experimental. YMMV.
