De-interlacing can be done for a variety of reasons, but by far the most common is to "stabilize" stills, especially freeze frames. Since every frame of video is actually made up of two sequentially captured fields, there can be a slight alignment in the fields. This is why interlaced video appears smoother than progressive video when there is a lot of motion, but also why a still can have "jaggies" on the detail if the frame in question has any movement associated with it. De-interlacing aligns the fields and gives a smoother looking image. This is most noticeable when viewing the image on your broadcast monitor since it is interlaced. Your computer monitor is progressive, so things there usually look pretty good, but if you're making anything that will be viewed on a TV (like a DVD) it's not an accurate representation.
I de-interlace video from time to time if it appears jerky, but this should be done with caution because it can also worsen the footage.
If you're going to be playing with HDV, make sure your field pominance setting is correct or all the footage will seem jerky. Also on the HDV topic, you'll want to have a nice healthy Mac and either FCP HD or FCP5 (preferably FCP5) in order to edit. Extra RAM and disk storage doesn't hurt either. I assume you understand that there is no standard (DVD-like) delivery system yet for HD yet.
