I agree with BMXTRIX...if you want good sound, why not have your store do the install for you? The harmony remotes are excellent, and easy to use. To program them, you connect them to your computer, go to the website, and tell it which devices you have...it sets the rest up for you. Then you just hit a "Watch DVD" or "Watch TV", etc. button.
Just as an additional equipment suggestion, since you mentioned the definitive equipment at the store, maybe you could check into the Definitive Tech Mythos Solo. ($699) One speaker for the price and space of three. Add to that a couple of Mythos Gems ($250 ea.) for surrounds, and a half-decent sub, and you'd still have plenty left for the cost of a receiver, dvd player, and an installer.
Then you could also go with a
NAD L70 receiver/dvd player (all-in-one unit), so you're not hooking up lots of extra devices.
This type of setup should be about the complexity of the bose setup, with much better sound. (IMHO, of course)
