Getting Itunes to show Subtitles for .mp4

[phil-likes-this]

Hi,

I have used handbrake to generate an .mp4 file and selected a subtitle track from the DVD. The result works well in VLC where I get an option to switch in on. In ITunes however, the subtitle &Audio field just shows the two audio tracks I included - no subtitles to select.
Changing the file extension to m4v made no difference either. Have been reading around on forum but couldnt find a solution. Maybe somebody can help?
I don't have a Mac, so Subler etc is unfortunately not an option. Many thanks

You must convert your subs to ttxt. Yamb claims to support srt to ttxt. It can also mux into mp4.
