Check out the latest beta of Subler (15 beta 3). He added support for 1080P tagging. It's also a pretty sweet tool that auto adds other meta tags (description, directors, etc).
yep, that now marks it as 1080P in iTunes.

It depends on the type of soft subs. vobsubs cannot be turned on, but closed captions can. Other text subs, like .srt, can also be added and turned on and off, but closed captions are probably the only type you'll see commercially.You can turn off and on subs now with the ATV2 -it allows selection of multiple soft subs. Just hold down the select button while a movie is playing and you can change the subtitle track or the audio track selected.
Nice if you want to include a commentary track in your movie.
OK having converted a few 1080p rips, i'm noticing that some (but not all) end up with the audio slightly out of sync (5.1 track).
source files are 1080p MKV with DTS tracks, and being re-converted to AC3 5.1.
any ideas?

The AppleTV doesn't play very well with AC3. Your best bet, if dealing with an MKV with AC3 is to convert just the audio to 5.1 channel AAC (which works a treat on the AppleTV).
I have found MP4Tools to be a bit unreliable, when it comes to producing audio in sync.
Given a MKV file I have the following procedure:
1) Extract the h264 stream from the MKV with Subler or ffmpeg. Convert it via Handbrake using CRF 20 to reduce file size, and make it High Profile 3.1 for good compatibility. Quality degradation is visually minimal, but it takes a few hours...
2) Extract the audio stream from the MKV with ffmpeg into a CAF file, (supports larger than 4 GB stream file size). Convert to AC3 and Dolby Pro Logic II via a combination of Compressor/afconvert/sox. I then have total control over the quality and things like downmix matrix, normalization and dynamic range compression.
Handbrake does not give you good advanced audio conversion options so far. Otherwise I would have used Handbrake for the audio as well. If they introduce more advanced audio options, as well as video pass thru, it would be great. I guess that won't happen anytime soon though.
i find that statement hard to believe, considering the default audio format for AppleTV files is AAC stereo and AC3 pass-thru 5.1
i've never had any issue with AC3 pass-thru until i've been using MP4Tools to remux an MKV DTS file to MP4.
The AppleTV doesn't support AC3 audio according to its tech specs here, further I've never been able to get any file with AC3 audio to play on my AppleTV.
There's more information about that, including steps on how to tell what audio is *actually* in your file in this thread: AVI, MKV, h.264... WTF Does it All Mean?
I think whatever utility you're using is actually transcoding it into AAC (and perhaps leaving the AC3 as well, aka 'passing it through').
What's important to note though, is that the AppleTV isn't playing the AC3, and also there's no reason to transcode 5.1 AC3 all the way down to stereo, when 5.1 AAC works a treat.

well i have stated AC3 pass-thru (a few times), so that clears up your mis-understanding.
From the pictures you posted, it looks like you're "Adding a 2-channel AAC", which means you're transcoding, which may not be necessary, and is definitely losing all the 5.1 goodness that the AppleTV can play.
When you pass through an AC3 5.1 and add an AAC 2-channel, then all the AppleTV sees is the AAC 2-channel. You're throwing away the surround sound needlessly, because the tool you're using is doing wonky stuff.
sorry that's incorrect. if you don't understand this process then please don't try to advise on it.
i've created many files using this process and i know precisely what audio tracks are produced at the end.
the MKV only has a DTS track. i am using MP4Tools to create a 2 channel AAC stereo track as well a 5.1 AC3-pass-thru audio track.
this is what the resulting file looks like...
That's exactly as I suggested was happening in my last post.
The AppleTV is ignoring the AC3, so all it sees is the AAC 2-channel track.
You're throwing away the surround sound that could be played on the AppleTV.
You should be creating an AAC 5.1 audio track (if you want to also have a 5.1 AC3, that's fine, but for the tenth time, the AppleTV doesn't play it whatsoever).
Does that make sense?
sigh.. it's NOT ignoring the AC3 track.
my amp plays the 5.1 track very nicely thank you.
a few issue with that solution.
1) i don't want to re-convert the MKV file I have. I am simply remuxing it from MKV to MP4 and leaving the h264 file untouched.
2) i don't want to change the 5.1 audio track to DPLII
iVI is unique at the moment in that it handles PGS subs and burns them into the encode (which is great for forced subs - the only type I care about),

That's just not correct. The Apple TV will see both tracks. It will default to the 2-channel AAC, that is standard operating procedure. But the 5.1 track is there and easily selected and used if wanted.
It defaults to the 5.1 track for me. Possibly because I have the aTV preference for audio set to Dolby Digital: On (as opposed to auto).
It was broken ?Ah, I think my confusion is because I haven't tried getting AC3 to work since it was broken a while back. My mistake.
Why not give the AAC 5.1 a shot, it's a more modern format and there aren't the same sync issues reported.
But am I correct that in order for it to be able to be imported into iTunes you cannot just have an AC3 5.1 track. From what I understand you can have an AC3 5.1 track as long as you also have an AAC 2 channel track. Please correct me if I am wrong.
