I am setting up a project for use by several people including one who is visually impaired. The requirement is to have a single video stream with multiple audio choices - Audio track 1 is narration, track 2 is just music and track 3 is an alternative narration for the visually impaired person.

The remote control on my desktop DVD player lets me select which audio to play but not before I've pressed the Play button on the First Play menu and the video content has started playing.

I'd like to be able to set up the choice of audio track to play on the First Play menu before the video starts but can't see how to set up text buttone to do that.

The obvious way of using 3 separate play buttons linked to 3 separate video/audio streams won't work because that would need too much space at reasonable encoding levele The programme is about 2 hours long.

Anyone got any ideas?

Thanks
