hi,
one good thing to do in your spare time is to toss every acronym at wikipedia, and do some reading.
you'll eventually find that DTS & Dolby labs are competing technologies for cinemas & home theaters & that some of those acronyms are successive releases of their respective products.
you'll get to understand the history of cinema & home theater too. once you digest all this, you'll better appreciate any setting your A/V reciever is showing you.
(it makes you sound so much smarter, too
)
Cheers,
Elden
