PS3 not showing all of my movies in the shared folder

I just purchased and setup a 1TB MyBookLive. My macbook pro can see the drive just fine. I created a shared folder and dumped all of my ps3 compatible movies into it. I then turned on the ps3 and searched for a media server. It found the MyBookLive. However when I click on the icon for the drive onl a small portion of my movies show up. All of the movies were encoded the exact same why and are in the same format. Any ideas what I could be doing wrong?

How many movie files do you have on your MBL?
