Here in Sydney Australia I use my Apple TV to view most content, using the Netflix and Disney apps mostly. The other day, I finished watching a Blu-ray with a DTS soundtrack, which was fantastic. When I switched to the Apple TV, the dynamics vanished. Does anyone here know what the compression is used by these companies? They claim HD video with 5.1 sound. The Apple TV is ending its signal to the Marantz AV7701, maybe an issue there?
