This makes sense. I had DVD(1), DVD(2) and HD(720P) selected. I wrongly (and dumbly) assumed these options were similar to the audio layers in that selecting more than one layer (embedding multiple audio tracks in one m4v) would allow the video to be played on various devices.

You are correct in your assumption that multiple audio tracks helps with playability on different devices. But the whole DVD(1) and DVD (2) was so users could encode the movie for different devices at one time. Especially holds true when your doing BD movies. I always encode at ATV2 and Universal or iPad.
******
In each profile what is the best video option? Example, DVD(1): "High Profile", "Apple TV 2" or "Universal". What is the quality for each profile and what is the best option to maintain video quality for playback on various m4v capable devices? I assumed "High Profile" was better than "Apple TV 2", but then "Universal" is thrown into the equation.
***
The rule of thumb is this. Encode to lowest common denominator. ATV2 is pretty near perfect quality in my opinion. I see some less than perfect when its clouds. Which I see on all of them. I have not done a comparison between High Profile and ATV2. Just pick a movie and select those two options and see which you like. Universal will fit most anything. It has the least amount of tweaks for performance, quality etc. As they say:
Quality
Size
Speed
Pick Two... thats all you can encode to. Two of those three.
*******
Perfect sense now, thank you. If I want a different encoding process I must use the "Custom" selection and the related command line for my particular needs as each profile is already customized for that particular device (ex Apple TV, iPad, etc.)
***
Correct. Heres how. Pick all the stuff you like and look at the advance window to see the options you have chosen. Now on the PC version it will show you the whole command line, while it apears the mac will not. You have to use the start of the command from mac.jedi's document and piece meal it together or even ask on HB forums.

On this I researched a lot. I realize a higher quality Bitrate of around 2000 with 2-pass encoding is more than necessary for the Apple TV 2. However at the recommendations of many I decided on this as to maintain the closest in video quality to the source DVD as possible and to (hopefully) future proof the movie rip. As well, playing the movie through XBMC allows the Apple TV 2 to use about every codec available and can force an output of 1080P, thereby bypassing the aTV's iOS downscaling of high def to 720P

I would beg to differ myself. First I would say that I can use ATV2 preset on a DVD and it is near perfect. Now with BD you may get something better. However I would suggest you use RF instead of kbps, just try it.. For normal DVD's use a number between 19-21, for BD use a RF of 20-22. Dont adjust the kbps and look at the quality.

Lord I'm such a blond sometimes. For some reason I bought AAC outputted in 2-channel (think I read that in another forums). There are so many I thought it was necessary to choose more than one for universal device capability. I'm guessing only one track is needed and the device itself (such as an iPad) will handle the audio by decoding it. If this is the case, what is the best audio (AC3 being constant):
AAC (Core Audio)
AC3 Passthru
AC3
Then with those choices what is the best:
Dolby Surround
Dolby Pro Logic II
6-channel discrete
Bitrate
I assumed AC3 with 6-channel discrete at 640 kbps was the best quality audio layer. Now I'm realizing that AC3 (5.1) w/ AAC (CoreAudio) and 6-channel discrete may be the best (and only necessary) audio layer.
*****
I always let the Batch Encode handle it. So it always does AC-3(5.1) and AAC in that order. So mine places through receiver perfectly fine, and iPad, computer perfectly fine. the iPad is smart enough to play the AAC track automatically.

You are the best! Thank you so much, I know I have been a complete PITA, and I can't imagine having to deal with my endless questions lol. I just want to do this once and do it right. Oddly I'm not a noob but I've become very humble in this learning process. THANK YOU!
I have no problems answering questions if I know (or think I know) lol. It gets me to think sometimes... Nothing wrong with that.
