I bought this mp4 player
http://www.dealextreme.com/details.dx/sku.1574 i cant watch any video files on this that i convert myself. I am not sure I'm doing this rigth. I can however download samples from here for the rockchip and play them. Can someone give me a step-by-step guide on how to convert fiels so i can use them here. btw this mp4 supports avi.
