    I'm having some problems with some of my DVD-rips that I've compressed with Handbrake and the new appleTV 2.2 software. The majority have been ripped with the 5.1 ac3 track and the same track in aac mode as well and these play fine. ATV plays the 5.1 version when it is enabled in the settings menu.

    The problem comes when I start ripping other tracks too.

    For example, there are a couple of commentary tracks I rip too so the tracks I select in handbrake are:

    main 5.1
    main aac
    commentary aac

    They play fine in VLC and I can switch between all the tracks fine, but on the ATV, it plays an aac track by default. Using the new audio track selection in the 2.2 software it brings up a menu with the following options:

    english (stereo)
    english (stereo)

    Both the first two options are ticked. Selecting the third one gives me ac3 5.1, but selecting either of the other 2 gives me the same aac track (which isn't the commentary track)

    The second problem occurs when I use different languages (eg anime) I've done some test chapters with the following tracks:

    english 5.1
    english aac
    japanese 5.1
    japanese aac

    Again when I play the files in vlc they are fine, but on the AppleTV I can see the following options:

    english (stereo)
    japanese (stereo)

    both the stereo tracks play ok (with the correct languages), but selecting either 5.1 track results in no audio at all.

    Having only 1 ac3 track seems to fix the problem - is this a limitation of the AppleTV? My anime collection is waiting to be ripped...

    I'm having the same problem with more than 2 audio tracks as well.

    It shows 2 playing at the same time, but I only hear one audio stream. Also the default audio is now 2.0 and not 2.1 (old tv show that didn't have 5.1).

    Fortunately I don't have a lot of TV shows with this setup, just a handful.

    Thankfully I've only got a handful too as I tried to only do commentaries I really enjoy (such as the Spinal Tap one). I've come up with some working theories which have yet to be proved wrong:

    1) ATV doesn't like more than one AC3 track per file (ie English and a foreign language track) - this results in neither giving any audio

    2) I think the extra tracks are both called the same thing: both the stereo AAC and commentary AAC are called "English (stereo)" on the ATV and this is why they both appear ticked as the ATV only goes on the name and not the content.

    To fix the 2nd problem, we need a tool that can rename the audio tracks to (for example): english, english (stereo), commentary (stereo).
