I generally recommend having everything coming in via HDMI to the home theater. Did you try the Direct TV to the home theater via HDMI?
I'm a complete newbie and hate hooking up electronics. I have the above new Blu-ray surround system that I just hookedup but I'm not convinced it's hooked up correctly and to optimize the features and best sound/picture quality.
I'm trying to hookup my Direct TV receiver, Vizio 41" TV and X-box so I have great sound/picture and can use the speakers when I play X-Box.
Here is how I fumbled around to get it connected right now. It was the only way I could get the surround speakers to work (once I switched the Blu Ray to "AUX"):
TV: HDMI-1 is connected to the HDMI-1 on the Direct TV receiver.
Direct TV receiver: Audio Out (white and red) are connected to the Aux In (white and red) on the Blu Ray.
(I haven't even attempted to get the X-box hooked up yet.) From the above hookup it just seems like there should be a better quality way to connect the satellite up with HDMI cables instead of RCA cables.
