I just recently bought a Toshiba laptop that plays blu rays. I've watched special features from Ten Commandments and POTC blu ray movies. I tried to watch the special features on my Fiddler on the Roof Blu ray and can't seem to access them. The player just starts playing the movie. I can't even access the menu. The software I'm using is Corel Windvd that came with the computer. Do you think the problem is with the blu ray disc or the software?
