I just want audio coming out from my speakers, not TV, but I understand HDMI is for audio and video. This may seem confusing. In other words, I want to use optical digital audio output for AV receiver audio connection. And I want to use HDMI for my HDTV connection. Both of these cables are coming from the HD DVD player. Many thanks to all that helped =)
You will get sound from both your HTIB system via optical and from your display via HDMI. Simple solution is to mute or lower the volume on the display to zero and just use your home theater speakers for sound. This way you can still use the displays speakers sometimes if you didn't want to have the home theater system always turned on (like late nite tv viewing when you don't want to wake the kids,wife..). You may notice a slight delay from one compared to the other which may produce an irritating echo, so just turn the display volume down when the home theater system is on.
You didn't mention what player you have or are thinking of getting but your home theater system needs to be able to bitstream decode mostly DD for a 3rd gen model (A3, A30, A35) or DTS for a 1st,2nd gen model (A1, XA1, A2, XA2). I say this because some HTIB systems only decode one or the other and not both.
