Your issue is not a Premiere Elements issue exclusive to Mac, and I expect the matter goes to the interaction with between the computer player and the DVD burner (AutoPlay).
I am strictly an Elements Windows user. When I use Premiere Elements (any version) on Windows 7, 8, or 8.1 64 bit for burn to disc and use a DVD-RW that has been written to once, I get the message from the burn software asking for permission to overwrite the original disc content. I need to click OK in order to continue. Have no other choice. But, once I do within a few seconds of the start, my CyberLink playback software that came with the burner opens to try to playback the original disc content. I need to rush to cancel to continue with my Premiere Elements burn to.in order to get to a successful conclusion (which I do).
I would start with Apple and setting AutoPlay.
Where are you setting the AutoPlay? In Windows, it would be in the Control Panel area. Does the computer give you control to
a. set what to do with a given type of DVD disc
as well as
b. which program should open DVD movies
