Well, I didn’t notice that you’re across the pond, so to speak, but we’ll make it work anyway. It’s just now lunchtime here in Texas, I’m on my break between classes.
I’m not sure what you really mean by SCART. For this discussion, I will ignore them for right now, or perhaps I will hit upon something that means the same thing. My set-up includes a Sony HTiB (Home Theater in a Box), DirecTV (the US version of Sky) and a Toshiba HD DLP (truly a miracle of technology). I will assume that your audio receiver can handle audio and video switching as well. I am also assuming that you do not want to hear anything through the TV’s built-in speakers.
Turn the power off on everything. Go ahead and leave the Sky box plugged in, since it takes so long for it to acquire the signal and boot up.
Let’s start with the Sony receiver. On mine, and perhaps yours, the HDMI is audio pass-through only. That may be the source of your problem. Still HDMI is useful in this set up. Connect and arrange the speakers as described in the HTiB’s instruction manual. Make sure that + is connected to + on everything. The subwoofer probably has its own coax connection. It will need a power source, too. Get it plugged in.
Okay, now let’s start connecting things. Using an HDMI cable, connect the HDMI on Sky to the HDMI in on receiver. Also connect the digital audio out from the Sky to the receiver. This may be optical or coaxial. Optical is best, but it can be delicate. Don’t kink the cable and be careful that it plugs in and stays plugged in. Make sure that the HDMI and audio are plugged into the same input group (such as “Video 1” or “Input 1”, or whatever nomenclature your receiver uses. They may not be in the same area of the jack panel.).
Now, let’s get the DVD connected. Using the same method as the Sky box, use an HDMI cable to connect the DVD to the receiver. Now, connect the audio out to the receiver. Again, use digital whenever possible. In my case, my satellite uses the optical audio port and the DVD uses the coaxial audio port (because we use the sat more than the DVD). Your needs may be different, or you may have more than one optical input. Again, make sure that you’re using the same input group for everything, this time “Video 2”, “Input 2”, “DVD” or whatever.
Now, on to the TV itself. Run an HDMI from the HDMI out on the receiver to the HDMI In on the TV. I suggest using HDMI 1 and saving HDMI 2 for your XBOX 360 or whatever. With this setup, your TV stays on HDMI 1 at all times. You won’t use it to control the volume or to change channels or inputs.
Now, let’s fire it up. First, turn on the receiver. Then, turn on the TV. Finally, turn on the Sky box. Make sure that the TV is on HDMI 1. On the receiver, select Video 1 or wherever you put the Sky box. You should see the Sky programming on the TV and hear it through the surround speakers. Put a disk in the DVD and get it playing. Switch the receiver to “Video 2” or wherever the DVD is. You should see the DVD on the TV and hear it through the surround speakers.
That help? Class coming in, so I gotta run. I’ll give you time to chew on this for a while.
