I used to be using the Sony BDP-S1. It had 5.1 analog out and I decided I was going to jump to the ability to decode 7.1. When I was using the Sony I would go in and set up the optical output for PCM and Rt/Lt output of both Dolby and DTS audio and decode the soundtracks with the Logic 7 processing in 7.1 mode. It sounded pretty good.
Now with the Panasonic trying to decode surround using Logic 7 isn't working out so well. I have found, and read in this forum, that the Panasonic BD80 does 2 channel mixes to stereo, but there does not seem to be any matrix information for my AVR 525 to work with. The Sony did seem to pass the matrix encoding a lot better. OR am I missing something in the settings? It would be nice to have this on some soundtracks and I find sometimes I prefer the matrix decoded over some discrete mixes.
I know all of this equipment is older but between the new economy, fear of problems I read about with equipment, I have decided to keep the older stuff a bit longer. My Panasonic is hooked directly to my overhead projector and I have not experienced any freezing problems. I had deduced personally that it was due to the jump from Panasonic, to AVR, to display, that was causing the freezing problems. Just my opinion though.
Anyway I am very happy with the HK 525 and Panasonic combo. The HK has internal level sets with bass management that is working very well for me I can select to do 6 channel (5.1) or 8 channel (7.1) inputs with bass management. The 525 then plays into external amps and the result is better than any local theaters to date.
With the DTS "feature" to replicate the surround channels into the back surrounds, I have been able to bypass that by choosing the 6 channel (5.1) inputs which then mute the two back surrounds. If I let the back surrounds play I notice some sound tends to wrap back between the two surround channels. I prefer not to let this happen, so I do like that I can shut the back two off if the soundtrack is 5.1. But back to Logic 7, sometimes I just liked the less discreet surround it could give, and IF it was possible to get that back, I would be nice. If not, Oh well, I am very pleased with being able to do DTS and Dolby with the analog outputs. Thanks.
