I put in a system when we finished our lower level this past winter. I won't call it a basement because it has 9' dry walled ceilings and a walk out thru it's own garage. That's where my R* lives.
We have Direct TV, Denon Surround sound thru two rear ceiling mounted speakers, the remote sub-woofer, two front ceiling speakers, two cabinet mounted speakers, a Sony Blu-Ray and a 50" Samsung LED w/ internal wireless and internet ready.
The sound on action movies is fantastic but after it was all wired we discovered we needed a separate audio cable for sound on the Blu-Ray.
The remote situation was a nightmare with three remotes needed. That confused the crap outta me and resulted in a $400 universal remote that hooks to one of my laptops and diagnoses itself and reprograms itself to correct whatever screw up I create. And I create them quite often.
But the sound is freakin' great.
Upstairs I added Samsung sound bar on the 46" LCD in the TV room and to tell the truth, except for the bottom end rumble and having sound come at you from all directions, it sounds awful good for a LOT less cash.
