it should be rockchip, it says so when i plug in the USB. I hope the pic is ok, i tried to get the screen to show up.. I don't have the sample vid anymore.. it was some fashion show.. named rockchip 1.8 or something ... I've tried about 10 converters, it says it accepts mpeg-4 coding, xvid, and divx I've tried them all with the resolution it gave me, and nothing.. I do have to hold it sideways to see the video though...
