There's no such thing as THX encoding for home cinema. THX is the title
of
George Lucas minimum specification for the quality of THeatre equipment
which he will alow to show his movies on.

Yes there is. THX uses a frequency equalisation curve which is optimised
for
theatres but not is so hot in a domestic living room. Also THX stands
for

I am not aware of THX being used on DVD's since they do not require
equalisation because they are digital.

All THX home recordings whether analogue or digital use 3db of
pre-emphasis
for frequencies above 2khz. This is not normally noticeable due to
absorbtion by room furniture. THX decoders include a defeat switch which
de-emphasises the signal but is not strictly necessary. THX decoders also
extract separate left-right surround from Dolby Pro-Logic recordings.

Dolby Pro-Logic II decoders already do that and IIx decoders have an
unlimited number of independent surround channels.



Thomas Holden eXperiment, nothing to do with THeatre.


Actually it was the name of George Lucas first movie THX 1138

Which has nothing to do with the name chosen for the certification
program,
or so Lucas claims.

Pro-Logic II does but Pro-Logic I did not.
