Thanks to Dave Lampson for his post. There's also a very informative
article on surround sound at the following URL:

[You're welcome, Steve. That article Steve recommends is a good, and
includes some interesting diagrams, but there are some erroneous, and
oddly confused, discussions of less impartant topics - such as the
statement that it's a three-way race between DVD-A, SACD, and DTS;
or that DVDs are played upside-down (only if the player does accepts
this, and few do). But otherwise it's worth reading, and includes good
discussions of classical recordings. -Dave]
