The source doesn't need to be deinterlaced before transferring to DVD. DVD is an inherently interlaced medium anyway. I believe the jaggies are the result of the telecine wobble. Since the transfer was captured to an interlaced medium, each field will be captured at a separate instance in time. If the film wobbles between two field captures from the same frame, then the fields won't exactly match up when weaved back together, hence the jaggies.
