I've been encoding various concert DVDs and now I'm encoding the British comedy show Red Dwarf. Along the way, I've noticed various issues with having multiple soundtracks and all of them are with AppleTV. That is to say that if I encode 2, 3 or even 4 soundtracks to a program, I can easily select any of the soundtracks in iTunes itself. But on AppleTV, there are issues. I've already read that you cannot select a different audio track if you only include say a stereo and a 5.1 Dolby Digital. It will only play the Dolby Digital unless you supposedly disable AC3 out. I'm not so sure about the latter (I got no output when I disabled it), but I can say I get no audio selection list with just two. For concert discs, I WANT to be able to access a stereo mix (mainly for my upstairs system, which is not surround). So I encoded two stereo tracks and a 5.1 track. This seems to work OK on AppleTV. I can access the audio menu by holding the select button and then selecting "English" for 5.1 or "English (Stereo) for the stereo tracks. I note that I see BOTH stereo tracks in the list, but when I select one, it checks BOTH of them and I don't care which one it's actually playing. The problem occurs when there are MORE than two soundtracks OR when both are 2.0 stereo tracks instead of a Dolby Digital track. For example, Season 1 of Red Dwarf contains 3 soundtracks. There are two commentary tracks and the regular audio. They are all 2 channel stereo AC3. So following the above example to ensure I can select the regular stereo track and don't get stuck listening to commentary tracks, I encode the main track twice and then add the two commentary tracks in Handbrake. In iTunes, things are as expected. I see all 4 tracks and I can access any of them directly from the playback audio dropdown option. On AppleTV, however, it shows all 4 tracks as "checked". They all just say "English (stereo)" and it doesn't matter which one I click on, it just plays the regular main track (not sure which one of the two copies). I cannot access any commentary tracks because they're all selected/checked and it does nothing to click on any of them. What gives here? Is AppleTV incapable of selecting different audio tracks unless it's just between Stereo and AC3? Is this a bug I should be reporting to Apple? (not that I believe they'd care since it doesn't involve them being able to sell me something). Would it help if I encoded them as something else like Dolby or would that just show up as stereo also and do the same thing? I've also noticed that Handbrake cannot encode some LPCM tracks (from what I read it cannot handle 24-bit ones and there's no way to know if you have 24-bit until you find that your stereo tracks are pure static). This makes the idea of encoding my entire DVD library to AppleTV seem impractical since between that issue and the inability to properly select audio tracks, the experience comes up a bit short, IMO. I've also noticed artwork issues with movies and tv shows. If I add an artwork file to a movie or tv show, it absolutely will NOT show up on AppleTV. It will show the so-called "poster frame" instead (frame taken from the actual content). Yet SOME of my material DOES show the artwork. I don't know about all cases, but I did discover if I select another video track at the SAME TIME as the one I'm trying to add art to and then use the artwork box for multiple items to add it (I can then remove it from the single track it doesn't belong to), then the artwork *WILL* appear on AppleTV every time. This seems like yet another odd glaring bug for AppleTV that I sincerely doubt Apple will have any interest in fixing but at least I found a way around it.
