How do home entertainment systems with surround sound work?

[rafaelhicks]

All I can find is that the system will work with dvd's. If I buy one and hook it up will the surround sound work with my cable tv?? Is there something special I have to do to make it work with my cable tv. What should I look for in a home entertainment system when purchasing one.

Most home theaters will have an audio input or some sort and not just work with the built in DVD/Blu-ray player. That input will vary depending on the surround sound unit you get (optical, digital, rca connections, or hdmi). Your cable box, satellite receiver or TV will need to have an audio output to plug into the surround sound system for it to play the sound through the setup you get. Sorry if this isn't enough information, but a lot of this stuff varies depending on your actual setup.
