Hi, I just got ther A500 today (manufactured december 2011) and tried to play some 1080p HD movie trailers on youtube, yahoo movies, movie websites etc..but the 1080p video is really choppy and not smooth at all. Is this normal? The 780p seems to play smooth. Some movie websites that have embedded video on the start page are also very slow (e.g. Grey). I also noticed google maps is terribly choppy. So is this normal or can I fix it?
