Actually Yamaha tech support told me it would not accept MPCM via HDMI & I called again today & asked to speak with a Tech Support Mgr. He confirmed the 661 will not accept MPCM via HDMI, it will only output PCM (or 2 channel). Even though the manual states it will, it will not!
I'm still a little confused as to exactly what 2 channel PCM means as opposed to MPCM, but I know that's a question I should ask over on the AV side of this forum, so I will. I do know, as I mentioned in an earlier thread, I've been running my HD-A2 off this 661 for about a year now and do get discreet sound from all channels even though the Yamaha's display only shows PCM.
But in any regard, the official (supposedly) word from Yamaha is that in order for me to get the lossless audio w/o having to upgrade to something like a 663, I will need to get the Panasonic 55 & utilize it's analog outs. Bummer, so I'm back to all the cables again!!
