The optical out port of the TV often just gives you 2-channel stereo when you are feeding from an external input. You have to refer to your TV manual or worse, test it out for yourself. I thought we have determined that you have just enough inputs in your receiver anyway to avoid doing this? Why not just connect video from the Bluray player using HDMI to the TV and then run another optical cable to your real receiver? Keep in mind optical only gives you 5.1 Dolby Digital/DTS at best (or it may be the 6.1 EX formats). You will need to either use HDMI to go LPCM 7.1 (decoding done in player) or TrueHD/Master Audio (bistreaming from player and decoding in the receiver).
This is what the manual of my 46" Panasonic plasma TV says:
TH46PZ80 manual wrote:When audio from other equipment connected to this unit via HDMI is output using “DIGITAL AUDIO OUT” of this
unit, the system switches to 2CH audio.
(When connecting to an AV amp via HDMI, you can enjoy higher sound quality.)
That's why we suggested you not to cheap out too much on the receiver (and speakers). After all, TV != receiver.
The Model M is not for the faint of heart. You either like them or hate them.
