I've read conflicting things on whether this happens in practice; The Dolby website, when I read it a couple of years ago, suggested it was. But I've read in various places, when I was researching this, that if your AV amp can't decode DD+. then feeding it to the amp may result in stereo.
It was a concern to me, as my bedroom AV amp (my old Yammy RX-V1500) can't decode DD+. Fortunately, my WDTV Live SMP sends regular DD via optical out, so not a problem. I have another WDTV Live SMP in the lounge which sends DD+ via HDMI to a Yammy RX-1900, which can decode it.
It can get a little confusing at times.
