I have been looking at home theater equipment for a while, but I am confused. I already have a blue-ray player, Directv HD DVR receiver, and a Wii to hook up to a receiver and five 5.1 Dolby speakers. Can anyone give me suggestions if I should buy a Home Theater system in a box or individual pieces and put them together as one unit? Let me know if you need more information from me. Thanks in advance.
