Hello, i just bought an xbox recently so i am still learning. When i bought my xbox used it came with an advanced AV pack, which apparently is used for connecting up better speakers. I am thinking of buying a set of small, mid-range, out of the box set of speakers. Nothing too glamorous or expensive as it is only in my small bedroom and i don't want to spend heaps of money. I can mount the speakers around my room and the sub will sit near my bed. At the moment i am using my humble 51cm Samsung TV with a MONO speaker ,lol. It was alright for playstation but for xbox, well your missing out on a lot of sound effects, thunderous bass and dynamic sound. A mono TV speaker just doesn't do the xbox any justice if you know what i mean, lol. Now my question - Does the Xbox incorporate its own internal dolby digital decoding or do i have to buy an amplifier/speaker package that includes it's own dolby digital? thanks for the replies, cheers.
