Kudos to National Center For Accessible Media (NCAM) for squeezing Apple to cough the info.

N.B. If your language is not supported by Apple you will get "unknown" when you try to select it in iTunes or QuickTime. For twisted reasons it wont show at all on iPhone. So choose english (eng)!!!

almost outdated now...

Now convert the SRT files to the TTXT format.

* Open a command-prompt window and change to the directory that contains MP4Box.exe and the source video file.
* Convert the SRT files to TTXT files: type (no quotes) "mp4box -ttxt filename.srt".
* Repeat for each SRT file.

Next, integrate each TTXT file into the source M4V.

* Type (no quotes) "mp4box -add filename.ttxt:lang=threeDigitLanguageCode targetMovieName.m4v. Here is a list of three-digit language codes.
* Repeat for each TTXT file.

When you have integrated all TTXT files into the movie, you must open the M4V in Dumpster (Windows or Mac) by dragging the M4V onto the Dumpster icon. The instructions below refer to Dumpster for Windows.

* Open the M4V in Dumpster.
* Double-click 'moov'.

The subtitle tracks you added to the movie can be found at the end of the 'trak' list. For example, if you added four subtitle tracks they will be the last four 'trak' entries. With this in mind...

* Double-click the first 'trak' that corresponds to your first subtitle track.
* Double-click 'tkhd'.
* Change Flags to $000001.
* Press the Apply button at the bottom of the window (note: press Apply after you make each change described below or else your changes will not be saved).
* Change Alternate Group to $0002.
* Double-click 'tkhd' to close.
* Double-click 'mdia'.
* Double-click 'hdlr'.
* Change Component subtype to $7362746c (this will change the type to 'sbtl').

Latest dev MP4Box build is able to do that in one step.

I hope this can be built-in to HandBrake.

If you are on mac you can use subler (http://code.google.com/p/subler/) to do it (and many other things)
The next version of HandBrake will automatically convert closed captions to tx3g for mp4 and srt for mkv. There have been no work for subtitles from non dvd sources at the moment.
