Hello. I just purchased this from best buy for 189.00 (great price). But I have to say I am not too impressed so far. All video playback is choppy. I have tried a number of video players and dowloaded respective codecs, but to no avail. How is it that a dual core processor cant handle a simple mp4 file? My Coby 7022 plays so far plays all mp4 files flawlessly and smoothly. Also, it doesnt play some games. It told me that it was not designed to play Asphalt 5, which is strange to me because it was offered in the tegra zone game app. I tried installing nova hd, but it froze. Any insights? Thanks.
