To be clear, I do not beleive there are any megachangers that will play the DVD-Audio format.

What I did was to load all my music discs starting from 1 and going up and the DVDs starting at the other end and going down so the colections aren't intermixed. We leave the unit set for all discs when we play music and it plays without repeating until we turn it off or get through the last cd. DVDs won't play automatically they just take you to the setup menu and wait for your to select setup or play.
