Motion estimation won't work around the subtitles because the stuff
behind them is moving but the text is staying in place. Also they just
tend to have sharp edges, which don't encode well.

Because someday you might, or you might want to loan your discs to a
friend who does, or you might find out the subtitles are horribly

keep the subs separate everything is flexible and you have many
options open. As soon as you burn them in you're stuck with them.
