Ok i will ad my $.02 cents.

A home theater in my eyes is as followed.

A display apropriate for the size room it is in.( not a 32" crt or lcd) greater than 50"
A surround processor minimum 5.1 but prefer 6.1 or 7.1
At least 150 watts a channel
At least 1 sub
Some kind of sound proofing/accoutic treatment
Ambiate lighting control
Internal lighting control of lights automated or manual.
Comfy couch or theater seats.
The rooms sole function is to watch some kind of programming or dvd or gaming .

Any thing else would be a media room or family room. It is a dual purpose room.

Anything from CC or BB or any other big box store does not constitute a home theater. Period, end of story.

If it says Sony or Bose it is in now way shape or form a theater. (G90 projo and other high quality projo's excluded)
