It is a step you might apply at rendering depending upon the target. If you are rendering for output through DV or DVD (or anything that targets the television), then you should keep the interlacing. If a DVD player is playing to a progressive display device, then you should let the player take care of the deinterlacing. However, if you plan to distribute the file over the Internet then you will want to deinterlace because the computer's progressive monitor is the most common display device. Even though some people might play back a video received through the Internet through something attached to their TV, not many of those devices properly handle interlaced playback. MLT handles deinterlacing (although not the greatest) when instructed (progressive=1 property set on consumer). It also does field-based rendering on certain, critical effects (e.g. composite) when you retain interlace.
