You can't hook up five speakers to your tv.
But, if the DVD player has red/white audio outputs (virtually all do) and your stereo TV has the standard red/white/yellow audio/visual inputs (many, not all, do), you can fed the sound, (red/white jacks) as well as the video (yellow jack) from the DVD to your TV.
The fact that you can play your DVD through your TV is a good sign. You might just need another set of sudio cables.
It isn't difficult. Read your manuals.
