I tried to play a rmvb video on my 4.3" Video player. The output is only 1.5 inches by 1 inch. It may be originally encoded for playing on small potable players. I am not sure how to confirm this. GSpot does not show its property. Is there any tool that I can convert it so that it can make ful use of my 4.3 " player ? Is this related to resolution of the video ? Any help would be greatly appreciated.
