PC Surround Sound
Thinking of setting up a home theatre system with surround sound? Under normal circumstances the easiest way to go about it is to get a packaged home theater system which typically comes with a DVD player. This is usually cheap and hassle free (if you don’t go for high-end stuff that is).
However, if you want to play surround sound content from downloaded video files (e.g. avi or mkv with ac3) then a PC is necessary. Using your PC (assuming you already have one) has the added obvious advantage that you don’t have to spend another dime on getting a DVD player.
