Scott Wilkinson ... Installed part II

Episode 1117

Scott is calling in from the CEDIA show, which is a custom design and installation show for home theater. He's been able to hear Dolby Atmos at home, which uses speakers to bounce sound off the ceiling to create a simulated 3D sound and he says it's pretty amazing. And the good news is that you don't have to upgrade your blu-ray player at all, you can just choose the Atmos sound track. But you will have to upgrade your AV receiver, which will set you back about $1000. But you can keep your speakers and just invest in the up-firing modules. So it's a half upgrade of your system.

How can old movies be in surround sound?

Episode 1098

Charles from New York, NY

Charles is annoyed with Netflix' attempts to encode movies in mono that are being decoded into stereo. He's also noticing that old movies on Blu-ray are doing the same thing. Is there a new 2 channel stereo to 5.1 surround conversion technology going on? David says that there are certain older movies that have remixed in Blu-ray and it's likely those are the movies that have been used, and Netflix is likely using that remixed master. Scott says that Dolby Pro-Logic can also take a standard stereo signal and spread it out over Dolby 5.1 surround.
