Can't Watch Korean Movie!

I just finished watching the movie "What Happens In Vegas".I had fun watching the film. I love Cameron Diaz. Anyway, the movie is great. It has a light story, a little comedy and of course the romantic twist.

I am scheduled to watch another film. It's a korean movie. But unfortunatel, my dvd rom won't read the dvd. I play the movie in my laptop but I don't know why it ejects everytime I push the play button. I know there's not a problem with the movie itself nor with the DVD-ROM.

According to a friend, perhaps theres a problem with the codec in the dvd or with the region thing. I don't know much about this. Perhaps i will just use an ordinary dvd player so that I can watch the movie.
