I have a blu-ray drive that I connected to my macbook pro under vista buisness using boot camp. I put in a blu-ray movie and a regular dvd and they both give me a crackling sound about once or twice every minute that is pretty annoying whenever I try to play a movie under cyberlink dvd. This happens when I use the external blu-ray drive (with a dvd and blu-ray) and the interal dvd drive (with a dvd) I'm watching a movie in hulu.com right now and I occasionally hear a very small crackle, but no where near as bad as with cyberlink. I'm not sure if this is a cyberlink problem or an audio problem under boot camp. Does anyone have more info on this? I'd really like to get it solved.
