Everytime I play a movie on iTunes, now when I have Windows Vista, it laggs and doesn't catch up to the sound. I have no clue why this is happening, and quite frankly, it is very annoying. It doesn't matter if it is a TV Show or a Movie I bought on iTunes, it laggs through the whole time! Recently, I bought a TV Show, and only AFTER I paused it, did it start to lag. I don't know if it is related, but it's worth a shot. Please, if anyone can help me, that would be great!
