Summary: When I hooked up my DVR to this unit - the surround sound does not pick up the sound from the DVR even though I have the HDMI and optic cables hooked up. Also I had expected this unit to have a port for headphone jack. Doesn't come with one. Really cheap system. I think I just wasted my money. Now that I took it out of all the packing material I really don't have a way to return it.
