I connected the two zone out terminals to the "Accurian HomePlug® Digital Audio Transmitter" which send the signal to a "Accurian™ HomePlug® Power Line Stereo Receiver/Amplifier" thru the power line. I went thru the menu and turned on the multi zone, made sure it was not muted and that it was on the correct input. I know the transmitter and receiver work because I connected an ipod deck to it and it worked fine. What am I doing wrong?

Make sure the source you've selected for zone 2 is connected to the 950 with an analog stereo cable. The second zone does not get a signal from digital inputs.

So if I select the FM tuner on the 950 does the signal go to the "zone out" terminals. Also I have the cd player set up for SACD with analog cable connections, does that mean I can only play the SACDs to the "zone out?"

The tuner will work with zone 2, as will the CD/SACD player if it is connected via analog to a stereo analog input (the six-channel analog input doesn't count, I don't think). Also, you can still listen to analog sources in the main zone.
