okay.not sure if you remember me,but heres my situation:sometime audio and video dont work.Not for the entire monitor,just video screens like on youtube.and no sound from music or videos.itunes works though.so its most likely just browser problem.but then it ried watching a dvd.sound worked but video didnt.i figured out that getting the new version of adobe flash player worked for the browser but didnt work for the dvd.The thing is I've had to download Adobe flash player 10.1 about 5 times already.What im asking is if anyone knows why the update doesnt stick.
