I finally bit the bullet on building a 5.1 home theatre system this year, and deliberately made the choice of keeping it as dumb as possible.
I went with;
* Denon AVR-X1800H
* Q Acoustics 5000 family (5020s surrounds, 5050s fronts, & 5090 centre)
* RSL Speedwoofer 12S
Now movies, music & games sound great, subtitles are no longer needed, and I don't have to worry about a single app! Just the windows shattering from the massive subwoofer
