Okay, here’s my problem. Dolby Digital output is turned on. None of my movies in VIDEO_TS folders that are Dolby Digital (AC3) surround, and any movie I have encoded as an AppleTV compatible movie with AC3 passthrough, will pass the surround channels to my Yamaha receiver. My Yamaha recognizes EVERY other source I have correctly (DVD, Blu-ray, HD Satellite), properly playing the surround tracks; but it recognizes AppleTV output as Dolby Digital ONLY when it plays the boot video. Then, everything I play is recognized as Dolby ProLogic. It’s not my Yamaha since I’ve switched inputs and the input works perfectly with any of my other sources.
How can I fix this?
