premier makes my 4:3 video small

[shadowofanubis6]

I put 3 mpeg clips into premier and added a little transition for them, but when i go to export > movie> and select any divx codec, the resulting video is small when i watch it in media player classic. I hope someone else has had this problem adn knows what im talkin about..., maybe it has somethign to do with... when i drag a video into the monitor, it shows the letterbox and video perfectly, when it is in the sequence window though... it just shows the video. I dont know..

It will be your export settings. Take screen grabs of the export screens so we can see what you are doing.
