RE: discs with DVD bit-rate audio tracks on BD...
There are numerous titles that have 448kbps or less Dolby Digital 5.1 tracks on them... for example: Monster House, Casino Royale, House of Flying Daggers, Tears of the Sun, Stealth, Into The Blue, Superman II, etc. Most commentary audio tracks are lower bitrate, too.
Yes I am connected via Optical. My receiver lites up the little "Analog - Dolby Surround" logo. The main display says Surround 6 (this is for 5 channel sound going to a 7 speaker/amplifier - which I have). When I put a plain old sd DVD in the player with the same connections and setup it lites up the "Digital - Dolby Digital" logo, and the main display says DD Surround EX. You can distinctly hear the differerence as the surrounds are less active and sound is less precisely located when it is in the Dolby surround mode - its more like slightly extended stereo.
As I said, I do not have this problem with my HDDVD player. Both the Toshibal XA2 HDDVD and the Panasonic BD-10a are hooked up through a component video (and digital optical) switching box that then feeds the B&K receiver. I found last night that if I change the setup to PCM sound (vs bitstream), I still get the same Analong-Dolby Surround, but I also get the audio during the preview section of the disc (Casino Royal). Previously with bitstream - I did not get any audio until the main menu appeared. Total Recall which advertises a Dolby Digital EX sound track still just gives me analog-dolby surround. DD EX tracks on regular DVD work fine. I did not check last night, but from previous experiments, I believe that when I have PCM selected in the setup instead of Bitstream, then even standard DVD's do not get DD, only dolby surround processing.
Does any one know for sure - If Blu Ray does NOT support standard DD ? Thanks for everyones help - PK
