Contrary to what the documentation used to imply, the -sameq option
does not necessarily mean same quality. This option only works in some
situations where the input and output share the same quantizer scale in
the same range (such as linear mpeg quantizer).
Most users will probably benefit more from adjusting qscale instead of
using sameq when encoding mpeg*. A value of 3-5 is a good balance
between quality and file size. A lower value is a higher quality.
