Thanks guys....I did a search (why didn't I think of that before?) and found out all about it. It's an OEM Dell product for playing DVD's, Bluray's in particular.
I had done an install of Mint "inside windows" and it was there as a separate partition for Media Direct and wondered if I should keep it since it is eating up space that I could use for Mint. So a big Mahalo to all who commented...Green Joe
