UPDATE (08/09/2012): in the comments section below, I elaborated on deinterlacing. Note that I'll devote a complete article / tutorial to these subjects (using X.264 / HandBrake / Episode to deinterlace etc.) some time. Before that, it's mostly HandBrake's (default) decombing that will be your best friend.
UPDATE (08/04/2012): THIS thread has a lot of discussion of the subject. Remember to prefer my statements to ones that state the opposite! (The thread is full of factual errors.)
