If its a HDTV with HDMI (all video and audio go through one cable) and the dvd player has HDMI then all you would need is an HDMI cable of the length you need. If there's no HDMI on the DVD then either use Component which is 3 video cables (red, blue, green) and 2 audio cables (red and white) or composite (yellow video and red and white audio) cables to hook it up. Now if its a WII you're talking about then they don't have an HDMI cable but you can get component cables for them . Ive heard there is an HDMI adapter you can buy for it but have not seen it or you can you composite. The sound bar should have the red and white audio hookups on it then would be connected to the red and white "audio out" of the TV. Some also have digital options but without knowing what you have I can't specify. Just think of it all like sex. most devices have an "in" and "out" on them. the device you want to send stuff out of has to have its "out" connections going to the "in" of whatever you want it to go to. depending on how good of quality you want it to look like it goes HDMI (best), component, S-video, composite, Coaxial cable (worst). and yes I am a genius when it comes to electronics
