hdtv and dvd player avi divx play back?.

I have a divx compatible dvd player and i'm having problems playing back my avi divx widescreen movies. My hdtv is a widescreen tv, my question is why does my widescreen movies play back with black borders on top and bottom on the tv screen when I watch movies with my dvd player?.



Hope you all can help me because it would really be great if I can watch my movies in full widescreen :).
