Trying to add a 2nd audio track (a commentary) to main video. I've added the video to timeline and 1st audio track and created sync track. Then i added 2nd audio track to timeline and tried audio sync track.. error, 'Media is already in use, cannot be overwritten'.

Did a search on maestro tutorials and multiple audio tracks and didn't find what i needed. Can anyone advise?? Thanks.

Edit: Maybe i don't have to do anything besides adding audio track and just compile? But would i be able to toggle between the 2 tracks with the audio button on the DVD remote? Would be nice to have a audio menu but not sure how I'd connect the 2nd audio to the video?? I usually only have 1 audio and it's the default (so no audio menu or connection needed).
