Also on Meridian's website the SpeakerLink capabilities has the following specs:
Encoded Dolby Digital and DTS passthrough (no decoding).

Does that mean it can be connected directly to the 861 (SL input), so the 861 can decode it for multi channel audio?

Can the HD121 replace the optical connection from the TV to get multi channel audio?
