This past weekend, I upgraded my Onkyo TX-SR806 to the HT-RC270. I did the upgrade primarily because earlier this year I purchased a Sony 3D TV (46NX711) and a Sony 3D Blu-ray player (BX57) and found out that the 806 was not able to pass through the 3D signals from the Blu-ray player to the TV (although it WAS able to pass through the 3D signals from my Scientific Atlanta cable box).
So far, things are running smoothly. However, I am curious about one thing. When I play a Dolby Digital 5.1 source from either my TiVo HD, my Scientific Atlanta 4240 HDC, or my AppleTV 2 (all of which are connected to the HT-RC270 via HDMI cable), the HT-RC270 listening mode automatically switches to "Dolby D." However, when watching a 3D or 2D Blu-ray disc from the Sony Blu-ray player (which also is connected to the HT-RC270 via HDMI cable), the HT-RC270 does not switch to Dolby D. In fact, I can't even find Dolby D as an option when playing from the Blu-ray player. Can anybody explain to me why this is?
Here's my set-up:
- The HT-RC270 is connected to the Sony TV via HDMI cable. I also have an optical audio cable running from the TV's output to the TV/CD input on the HT-RC270.
- The Blu-ray player is connected to HDMI 1 and assigned to the BD/DVD input.
- The TiVo is connected to HDMI 2 and assigned to the VCR/DVR input.
- The Scientific Atlanta box is connected to HDMI 3 and assigned to the CAB/SAT input.
- My Wii is connected by component cables to Component 1 and assigned to the Game input. This is the only device I have not yet tested.
- My AppleTV (2nd generation) is connected to HDMI 5 and assigned to the PC input.
- I have a 5.1 set-up with Paradigm front and center channels, JBL back channels, and a Paradigm subwoofer.
Incidentally, I also have a Sony 400 disc DVD changer. When I tried connecting it to the HT-RC270 to HDMI 4 and assigning that input to Game (keeping the Wii off), it registered "Dolby D" for the previews on the Up disc, but then switched to THX Cinema when the main feature started.
I'm nearly positive that the Blu-ray player and the 400 disc changer always registered "Dolby D" on my SR806 (at least when I had a Dolby DVD or Blu-ray as the source. So, I'm very confused as to why the HT-RC270 is not behaving the same way. I would greatly appreciate an explanation as to when and why "Dolby D" is automatically selected versus some other listening mode.
Thanks in advance.
