Just as the title says. Lately I've been enabling Dolby Surround on my Denon 3700 to decode older shows that are available in stereo only. From previous experience, these sources usually seem to be between 96 and 160kbps.
For music, 160kbps MP3 is juuuust passable - the highs aren't ear piercing with underwater sounding artifacts. Voice is fine except for the fact that listening fatigue sets in sooner.
For stereo encoded 5.1 surround, 160kbps is ______? The sound from left/right rears is supposed to be comprised of information only 90 degrees out of phase on the left/right fronts- I can't help but think the phase shift applied to the original analog track is compressed away. The garbled junk I hear from my rears tells me this might be the case.
Thoughts?
I hope I'm in the right subforum!

I guess I didn't really pose my question.
Are the TV shows streamed in stereo (particularly/especially shows made mid 90s to late 00s) encoded for Dolby processing? Or are they specifically mixed for stereo playback only? Do they even make seperate mixes? I don't know general practice for video - my hobby has been stereo audio only up to 1.5 years ago.
If it's Dolby encoded stereo, is changing a receiver's sound mode to "DSurr" (which does make 5 channes out of any 2) the correct way to decode Dolby Surround? And is my disappointing experience the result of lossy compression compressing away the inaudible phase shift applied to some sounds for processors to send them to the rear channels? Lossy compression like MP3 works by removing inaudible/unperceived aspects of sounds in recordings, so it kind of makes sense to me that the quality of Dolby encodings would be affected.
Or am I doing it wrong? Lol
