In the item description reads: "Set the speaker system according to your wishes, and connect up to four audio sources such as PC, game console, iPod, DVD player and much more." Unfortunately, there is no mention here that at a use with the DVD player, an additional decoder needs, which is so expensive to buy that one ultimately can bring a real (ie intended for TV's) surround system.
For the deception's been a star deduction. If you want the sound system but on the PC, games console or MP3 player to use you here for comparatively little money a really great device combination!
