First post so first things first - hello all! I have been building my digital movie collection the past few months through both iTunes purchases and backing up my DVDs and Blu-Rays. I've spent a lot of time troubleshooting, researching, and adjusting my process. My main concerns have been with AUDIO issues for I am in the camp that says the audio in a movie is just as important as the video. My biggest wish right now is that the AppleTV would allow the option to just passthrough audio bitstream to allow the reciever to handle any decoding of licensed surround audio formats (Dolby, DTS, and their various versions). This is a "hands off" approach - much like blu-ray players and game consoles allow for - I mean, what modern A/V reciever doesn't have the capability to decode most every surround format??? Here is my setup: iMac (late 2012 27") running iTunes as the media organizer. Hard wired networked to the Apple TV(3). HDMI out of ATV to A/V Reciever. HDMI to 60" Plasma. Full 7.1 speaker setup. I am ripping with an external USB3.0 LG blu-ray drive. I rip with MakeMKV and usually only take the primary title/audio. I convert with Handbrake and am currently fiddeling with sound options. Im currently including the AC3 passthrough and a Dolby Pro Logic II track in each .m4v file. It looks like, for now, I am limited to AC3(DD5.1) with this setup. With my A/V setup my personal preference is to listen to movies in DTS-MA 7.1, or second choice, Dolby TrueHD 7.1. Dolby/DTS EX/ES are next down the lsit. DD5.1 even furthur down This is my personal preference and what sounds best to me on my system. Obviously, the only way I'm going to get my preferred audio is directly from the BR Disc. Thats OK for now - I recently bought X-MEN Days of Futures Past which is a DTS-MA 7.1 mix and it just blew me away - having discrete rear surround in addition to regular surround is just awesome to me. Again, a bitstream passthough option from AppleTV would allow me to enjoy full 7.1 surround with my Mac/ATV home theater media setup...is it that hard? In summary, I like where my setup is going and it is working well. The clear bottleneck is AppleTV demanding to decode surround formats (and only outdated inferior formats at that) rather than allowing a bitstream passthrough for the A/V reciever to handle that job.
