Newhome:sorry to ask this again would two hdmi outputs be enough to run plasma, ps3, blueray, sateline on the amplifier or am i getting confused about how i should be wiring this, to be getting the sound from all my devises from the speakers.
Well you need to be sure you're not getting mixed up between HDMI inputs and outputs on your amp. The inputs are where you're plugging the PS3 and blu-ray into (and Sky normally, but I'll explain that below). The outputs are what you connect to the plasma screen (only one, usually).
So, you would connect the PS3 and blu-ray player into two of the INPUTS on your amp, then you would connect one OUTPUT to your plasma screen. So that just leaves Sky. Normally you would connect the HDMI (I assume this is SkyHD?) from the Sky box to the amplifier, but if you do this you won't get surround sound from Sky because the box doesn't pass it down the HDMI cable, only stereo. You need to connect the optical digital output from the Sky box to the amp to get surround sound.
What this means is, if your amp only has two HDMI inputs, you can connect the Sky HDMI directly to the plasma (assuming that your plasma screen has two HDMI inputs!), get the surround sound via the optical cable, and then use the two HDMI inputs on the amp for PS3 and blu-ray, problem solved.
Does that make sense?
