You should be aware that for an HDMI Input to your TV, the Optical Out from the TV is only Two-Channel. (The Optical Out is multi-channel if the source is the TV's OTA tuner(s) or the TV's internal Qam tuner if so equipped.)Halfsek said:
EDIT: I believe that TVs with Cable Cards also would pass that audio as multi-channel on the TV's Optical Out.
