No, it doesn't. After you reach a certain limit with MPEG-2, you are
just throwing useless bits at it. For 1080/24p on a multi-pass compressor,
you can do the job with 25Mbps and have already reached the "throwing
useless bits at it" point.

Because of this, a 25GB disc is more than enough for a 2-hour movie,
and anything more is just going to be filled with lots of useless SD
extras.
