Stereo - no surround sound
Setup of my 2nd Gen ATV has gone very smoothly. Only one problem. All movies play as stereo, even when there is a 5.1 surround track. When I go into the Audio settings, if I turn Dolby Digital from Auto to On and then play a movie, my receiver say "Stereo Downmix". My ATV and receiver are connected by an HDMI cable.
Any ideas?
Cheers!
