I've been upgrading my home theater setup piecemeal and have hit the first real snag that I'm unable to figure out on my own. I'm hoping someone will be able to lend a hand.
I have a Samsung LN46A750 HDTV with the latest firmware (1012.2). I just received a Samsung BD-P4600 Blu-Ray player. I have it wired directly to the TV via HDMI. The only older link in this system is a (by today's standards) ancient Yamaha RX-V595 receiver that I'm quite fond of. It has Dolby Digital 5.1 decoding via optical input, but no HDMI support, obviously. I've got the optical audio output from the TV wired into the DVD/LD optical audio input on the receiver. When I watch DVDs, however, (Blu-Ray or otherwise), the front of the display indicates "Pro Logic" rather than Dolby Digital as I would have seen with my previous (standard DVD) setup.
In my previous setup, I had a standard-def DVD player with the component video out routed to the TV and the optical audio out routed directly to the receiver (same input I'm using now). I would see the front display of the received switch to "Dolby Digital" when watching the main feature on a disc.
The brief listening tests I've done seem to suggest that I AM getting output from all speakers (center, main, and surrounds) in my system even though I'm in Pro Logic. I haven't had time to do any extensive testing to check whether placement in the soundstage is as I would have expected previously, but I wonder if anyone had any advice on how to get the comforting "Dolby Digital" processing on my receiver back on with this configuration. Any help would be greatly appreciated.
