My DVD player does not play surround sound

I have a problem with my DVD player: it does not play videos with surround sound. As an effort to rectify this, I connected it to my Mac which contains surround sound in the Audio/MIDI setup.
I also tested it by using with a Firestudio and a Presonus FP10 sound card. The DVD player still failed to play surround sound. Is it correct to think that the DVD player has no support for surround sound?
If so, does the packaging for the DVD player come with the information? Your assistance will be highly appreciated.
