I found a full screen player called mvideo.Mvideo playback 128×96 videos full screen.If you want watch videos bigger resolution and widescreen use pocket divxencoder (search google very small app) and change video orientation options and encode any format.After this open xilisoft 3gp converter and convert your video to 3gp and chose resolution 112×140.Not full screen but bigger than default media player.If mvideo not open videos,uncheck mirrored option.
