Welcome to the forums!
Maybe a kind moderation man will move this to a more suitable forum!
Your question is rather broad, so i'll just get you started!
For starters, you need a display device, be it a tv, projector, plasma, all depending on your desires! Then you need a dvd player or whichever other sources you need. If you have opted for plasma or projector, you could also look for a video processor which would enhance the picture quality.
Soundwise, you need a multichannel amplifier, one that does dolby digital and dts. To go with this you need a speaker package, this could be 5 speakers, 6 or even 7 depending on your amp and how many speakers you want! Further, a subwoofer is nice addition for good bass.
Thats the basics, if you go and read through the other forums you can find more specific detail. Dont forget to use the search facility, if you cant find what you want, someone will try and answer you queries!
