    I've got a bunch of MKV files with surround sound audio tracks (mostly DTS 5.1) that I'd like to convert to M4V so I can import them into iTunes. I've tried a few conversion apps—Subler, iVI, iFLicks—and the resulting files seem to have 2 channel audio. Am I correct? Can iTunes play any surround sound formats? If so, what settings in any of those apps should I use?

    iTunes and Apple TVs can play m4v files with AAC stereo tracks and Dolby Digital 5.1 tracks (AC3). If iTunes, you need audio equipment that can handle Dolby Digital - iTunes just passes it on.

    The canonical file from Apple contains video, AAC audio, AC3 audio, subtitles, chapter track, in that order. For maximum flexibility and compatibility your files should be in that format. I know that MP4Tools will convert DTS to AAC and AC3, I do not know about the others.

    iTunes supports Dolby Digital 5.1. I don't use any of those apps for conversion, I use Handbrake to do the transcoding and Subler only to update the metadata and artwork.
