My dvd is stuck in my disk player.

I was watching a movie on my apple external DVD player and it worked fine. When I ejected it, it unmounted the disk player, but didn't eject the disk. Without thinking, I unplugged it and closed my computer. Now, when I plug in my DVD player, disk utility doesn't even see the DVD player. The player just makes what sounds like a read-head move and completely shuts off. How am I supposed to get my dvd out of this thing?
